List of Olympic Games scandals, controversies and incidents

The Olympic Games is a major international multi-sport event. During its history, both the Summer and Winter Games have been the subject of scandals, controversies and incidents.

Cheating, such as the use of performance enhancing drugs by athletes, has regularly affected the Olympic Games. Some countries have boycotted the Games on various occasions, either as a protest against the International Olympic Committee or the contemporary politics of other participants. Some countries have also been banned from the Olympics, such as the defeated countries after both World Wars or South Africa under apartheid. Other controversies have included decisions by referees and gestures by athletes.

Summer Olympics

1896 Summer Olympics – Athens, Greece

• Marathon runner Spyridon Belokas won the bronze medal, but later admitted to covering part of the course by carriage, and was disqualified.

1900 Summer Olympics – Paris, France

• The Games were considered a planning and organizational failure. In athletics, organizers did not allow enough room for throwing events, leading Hungarian discus throw gold medalist Rudolf Bauer to throw three of his attempts into the crowd. Swimming events were held in the River Seine, which was a sewage outflow for Paris.

1904 Summer Olympics – St. Louis, Missouri, United States

• Marathon runner Frederick Lorz reached the finish line first and was about to be awarded the gold medal before it was revealed he had not run the entire race. Lorz, suffering cramps, had dropped out of the race after nine miles and hitched a ride back to the stadium in a car. When the car broke down at the 19th mile, he re-entered the race and jogged across the finish line. Upon being confronted by race officials, Lorz admitted his deception and was disqualified.
• Anthropology Days, an unofficial part of the Games, involved indigenous peoples from around the world being displayed and performing in sporting events that they had not been prepared for.

1906 Intercalated Games – Athens, Greece

• Peter O'Connor, an Irish athlete representing Great Britain, climbed up the Olympic flagpole with an Irish flag in order to protest being considered a British competitor.

1908 Summer Olympics – London, England, United Kingdom

• Grand Duchy of Finland competed separately from the Russian Empire, but was not allowed to display the Finnish flag.
• In the men's 400 metres, American winner John Carpenter was disqualified for blocking British athlete Wyndham Halswelle in a manoeuvre that was legal under American rules but prohibited by the British rules under which the race was run. As a result of the disqualification, a second final race was ordered. Halswelle was to face the other two finalists William Robbins and John Taylor, but both were from the United States and decided not to contest the repeat of the final to protest the judges' decision. Halswelle was thus the only medallist in the 400 metres, a race which became the only walkover victory in Olympic history. Taylor later ran on the Gold medal-winning U.S. team for the now-defunct Medley Relay, becoming the first African American medallist.

1912 Summer Olympics – Stockholm, Sweden

• American athlete Jim Thorpe was stripped of his gold medals in the decathlon and pentathlon after it was learned that he had played professional minor league baseball three years earlier. In solidarity, the decathlon silver medalist, Hugo Wieslander, refused to accept the medals when they were offered to him. The gold medals were restored to Thorpe's children in 1983, 30 years after his death.
• Portuguese marathon runner Francisco Lázaro became the first Olympic athlete to die in competition after collapsing on the track. Heat exhaustion, sunstroke, heart problems, and a possible electrolyte imbalance are thought to have contributed.

1916 Summer Olympics (not held due to World War I)

• The 1916 Summer Olympics were to have been held in Berlin, German Empire, but were cancelled because of the outbreak of World War I.

1920 Summer Olympics – Antwerp, Belgium

• Budapest had initially been selected over Amsterdam and Lyon to host the Games, but as the Austro-Hungarian Empire had been a German ally in World War I, the French-dominated International Olympic Committee transferred the Games to Antwerp in April 1919.
• Austria, Bulgaria, Germany, Hungary, and Turkey were not invited to the Games, being the successor states of the Central Powers which were defeated in World War I.
• The final of the football tournament was won by Belgium after the Czechoslovakia team walked off the pitch while the score was 0–2 to protest a referee's decision.

1924 Summer Olympics – Paris, France

• Germany was again not invited to the Games.
• In the boxing middleweight quarter final, British boxer Harry Mallin showed the referee a bite mark on his chest inflicted by French opponent Roger Brousse. The referee nonetheless declared Brousse the victor. A Swedish official protested on Mallin's behalf, and Brousse's previous opponent, Argentine Manolo Gallardo, complained that he had also been bitten. Brousse was disqualified, and Mallin went on to win the gold medal.

1928 Summer Olympics – Amsterdam, Netherlands

• The women's 800 meters race caused controversy after several women reportedly collapsed at the finish line. As a result, races longer than 200 meters were banned for women until the 1960 Olympics.

1932 Summer Olympics – Los Angeles, California, United States

• Nine-time Finnish Olympic gold medallist Paavo Nurmi was found to be a professional athlete and banned from running in the Games. The main orchestrators of the ban were the Swedish officials that were the core of the IOC bureaucracy, including IOC president Sigfrid Edström, who claimed that Nurmi had received too much money for his travel expenses. Nurmi did, however, travel to Los Angeles and kept training at the Olympic Village. Despite pleas from all the other entrants of the marathon, he was not allowed to compete at the Games. This incident, in part, led to Finland refusing to participate in the traditional Finland-Sweden athletics international annual event until 1939.
• After winning the silver in equestrian dressage, Swedish rider Bertil Sandström was demoted to last for clicking to his horse to win encouragement. He asserted that it was a creaking saddle making the sounds.

1936 Summer Olympics – Berlin, Germany

• In 1931, the International Olympic Committee (IOC) selected the German capital city Berlin as the host city of the 1936 Summer Olympics. However, following Adolf Hitler's rise to power in 1933, the plans for the Olympic Games became entangled with the politics of the Nazi regime. Hitler regarded the event as 'his' Olympics and sought to exploit the Games for propaganda purposes, with the aim of showcasing post-First World War Germany. In 1936, a number of prominent politicians and organizations called for a boycott of the Summer Olympics, while other campaigners called for the games to be relocated.
• Lithuania was not invited by Germany due to the Memelland/Klaipėda region controversy.
• Under the proposal of the autonomous Government of Catalonia, the newly elected Popular Front government of the Second Spanish Republic decided to boycott the Berlin Games entirely and, together with labour and socialist groups around the world, organized an alternative event, the People's Olympiad, held in Barcelona, Catalonia. The event did not take place however; just as the Games were about to begin the Spanish Civil War broke out and the People's Olympiad was canceled.
• In the United States, there was considerable debate about boycotting the Games. A leading advocate of a boycott was U.S. athlete and politician Ernest Lee Jahncke, the son of a German immigrant, who was an IOC member before being expelled from the IOC for his views.
• International concern surrounded the ruling German Nazi Party's ideology of racial superiority and its application at an international event such as the Olympics. In 1934 Avery Brundage undertook a visit to Germany to investigate the treatment of Jews. When he returned, he reported, "I was given positive assurance in writing ... that there will be no discrimination against Jews. You can't ask more than that and I think the guarantee will be fulfilled." However, a number of record-holding German athletes were excluded from competing at Berlin for being racially undesirable, including Lilli Henoch, Gretel Bergmann and Wolfgang Fürstner. The only Jewish athlete to compete on the German team was fencer Helene Mayer.
• Jewish American athletes Sam Stoller and Marty Glickman were originally selected to compete in the 4x100 meter relay, but were replaced on the day of the race by Jesse Owens and Ralph Metcalfe, despite Owens' protests. Glickman has claimed the decision was made to keep Jewish athletes off the podium "so to not embarrass Adolf Hitler".
• Hitler's decision not to shake hands with American long-jump medal winner Jesse Owens has been widely interpreted as a snub of an African American; however some commentators have noted that Hitler missed all medal presentations after the first day as he only wished to shake hands with German victors. Owens himself was reported to have been magnanimous when he mentioned Hitler. After the Games however, Owens was not personally honoured by President Franklin D. Roosevelt.
• The Irish Olympic Council boycotted the games as the IAAF had expelled the National Athletic and Cycling Association for refusing to restrict itself to the Irish Free State rather than the island of Ireland.
• In the cycling match sprint final, German Toni Merkens fouled Dutch Arie van Vliet. Instead of disqualification, Merkens was fined 100 German reichsmarks and kept the gold medal.
• In one of the football quarter-finals, Peru beat Austria 4–2 but Austria nonetheless advanced to the next round under very controversial circumstances. As a sign of protest the complete Olympic delegations of Peru and Colombia left Germany.

1940 and 1944 Summer Olympics (not held due to World War II)

• The 1940 Summer Olympics were scheduled to be held in Tokyo, Japan, but were cancelled due to the outbreak of the Second Sino-Japanese War. The government of Japan abandoned its support for the 1940 Games in July 1938. The IOC then awarded the Games to Helsinki, Finland, the runner-up in the original bidding process, but the Games were not held due to the Winter War. Ultimately, the Olympic Games were suspended indefinitely following the outbreak of World War II and did not resume until the London Games of 1948.

1948 Summer Olympics – London, England, United Kingdom

• The two major Axis powers of World War II, Germany and Japan, were suspended from the Olympics, although Italy, their former ally, participated. German and Japanese athletes were allowed to compete again at the 1952 Olympics.
• The Soviet Union was invited but chose not to send any athletes, sending observers instead to prepare for the 1952 Olympics.

1952 Summer Olympics – Helsinki, Finland

• The Republic of China (Taiwan) withdrew their athletes due to the participation of the People's Republic of China.

1956 Summer Olympics – Melbourne, Australia and Stockholm, Sweden

• Eight countries boycotted the Games for three different reasons. Cambodia, Egypt, Iraq, and Lebanon announced that they would not participate in response to the Suez Crisis during which Egypt had been invaded by Israel, the United Kingdom, and France after Egypt had nationalized the Suez Canal. The Netherlands, Spain, and Switzerland withdrew to protest the Soviet Union's invasion of Hungary during the 1956 Hungarian Revolution and the Soviet presence at the Games. Less than two weeks before the Opening Ceremony, the People's Republic of China also chose to boycott the event, protesting the Republic of China (Taiwan) being allowed to compete (under the name "Formosa").
• The political frustrations between the Soviet Union and Hungary boiled over at the games themselves when the two men's water polo teams met for the semi-final. The players became increasingly violent towards one another as the game progressed, while many spectators were prevented from rioting only by the sudden appearance of the police. The match became known as the Blood in the Water match.
• The advent of the state-sponsored "full-time amateur athlete" of the Eastern Bloc countries further eroded the ideology of the pure amateur, as it put the self-financed amateurs of the Western countries at a disadvantage. The Soviet Union entered teams of athletes who were all nominally students, soldiers, or working in a profession, but many of whom were in reality paid by the state to train on a full-time basis. Nevertheless, the IOC held to the traditional rules regarding amateurism for athletes from non-Communist countries.
• Due to quarantine issues, the equestrian events were held in Stockholm, Sweden.

1960 Summer Olympics – Rome, Italy

• In the modern pentathlon, the team from Tunisia cheated by attempting to pass off their strongest fencer as each of their three athletes, using his mask to conceal his identity. The ruse was discovered and the Tunisians were disqualified from the fencing portion.
• The team from Taiwan was made to compete under the name "Formosa", and marched in the opening ceremony with a sign reading "Under Protest".
• In the men's 100 meter freestyle event, American Lance Larson and Australian John Devitt both appeared to touch the wall first, with half of the six judges each thinking Larson and Devitt had won. Head judge Hans Runströmer controversially gave the gold medal to Devitt.
• Danish cyclist Knud Enemark Jensen collapsed and died during the men's team time trial event after fracturing his skull. The death was blamed by some on performance enhancing drugs, and acted as an impetus for future drug testing at the Olympics.

1964 Summer Olympics – Tokyo, Japan

• Indonesia and North Korea withdrew after the IOC decision to ban teams that took part in the 1963 Games of the New Emerging Forces and a three-year violent conflict, the Indonesia–Malaysia confrontation.
• South Africa was suspended from the Olympics due to its apartheid policies. The suspension would be lifted in 1992.
• Australian swimmer Dawn Fraser was arrested for allegedly stealing a flag from the Tokyo Imperial Palace, and was banned by the Australian national federation for ten years.

1968 Summer Olympics – Mexico City, Mexico

• 1968 Olympics Black Power salute: Tommie Smith and John Carlos, two black athletes who finished the men's 200-metre race first and third respectively, performed the "Power to the People" salute during the United States national anthem. Peter Norman, a white Australian who finished in second place, wore a human rights badge in solidarity, and was heavily criticised upon returning to Australia.
• Věra Čáslavská, in protest to the 1968 Soviet-led invasion of Czechoslovakia and the controversial decision by the judges on the Balance Beam and Floor, turned her head down and away from the Soviet flag whilst the anthem played during the medal ceremony. She returned home as a heroine of the Czechoslovak people, but was made an outcast by the Soviet dominated government.
• Students in Mexico City tried to make use of the media attention for their country to protest the authoritarian Mexican government. The government reacted with violence, culminating in the Tlatelolco Massacre ten days before the Games began and more than two thousand protesters were shot at by government forces.
• The first Olympic disqualification for a banned substance occurred in the modern pentathlon competition, after Swedish athlete Hans-Gunnar Liljenwall drank two beers before the shooting portion, disqualifying the Swedish team from their third place finish.

1972 Summer Olympics – Munich, West Germany

• The Munich massacre occurred, when members of the Israeli Olympic team were taken hostage by the Palestinian terrorist group Black September. Eleven athletes, coaches and judges were murdered by the terrorists.
• Rhodesia was banned from participating in the Olympics as the result of a 36 to 31 vote by the IOC held four days before the opening ceremonies. African countries had threatened to boycott the Munich games had the white-minority-ruled regime been permitted to send a team. The ban occurred over the objections of IOC president Avery Brundage who, in his speech following the Munich massacre, controversially compared the anti-Rhodesia campaign to the terrorist attack on the Olympic village (see Rhodesia at the Olympics).
• In the controversial gold medal basketball game, the US team appeared to win the gold medal game against the Soviet team, but the final three seconds were replayed three times until the Soviets won.
• The 1972 Olympics Black Power salute, also known as the Forgotten Salute.
• At the end of the men's Marathon, a German impostor entered the stadium to the cheers of the stadium ahead of the actual winner, Frank Shorter of the United States. During the American Broadcasting Company coverage of the event, the guest commentator, writer Erich Segal, famously called to Shorter "It's a fraud, Frank."
• In the men's field hockey final, Michael Krause's goal in the 60th minute gave the host West German team a 1–0 victory over the defending champion Pakistan. Pakistan's players complained about some of the umpiring and disagreed that Krause's goal was good. After the game, Pakistani fans ran onto the field in rage; some players and fans dumped water on Belgium's Rene Frank, the head of the sport's international governing body. During the medals ceremony, the players staged protests, some of them turning their backs to the West German flag and handling their silver medals disrespectfully. According to the story in the Washington Post, the team's manager, G.R. Chaudhry, said that his team thought the outcome had been "pre-planned" by the officials, Horacio Servetto of Argentina and Richard Jewell of Australia.

1976 Summer Olympics – Montreal, Canada

Countries boycotting the 1976 (yellow), 1980 (blue) and 1984 (red) Summer Olympics

• In protest against the New Zealand national rugby union team's 1976 tour of South Africa, controversial due to the regime's apartheid policies, Afghanistan, Albania, Burma, El Salvador, Guyana, Iraq, Sri Lanka, Syria and Tanzania, led a boycott of twenty-two African nations after the IOC refused to ban New Zealand from participating. Some of the teams withdrew after the first day. The controversy prevented a much anticipated meeting between Tanzanian Filbert Bayi—the former world record holder in both the 1500 metres and the mile run—and New Zealand's John Walker—who had surpassed both records to become the world record holder in both events. Walker went on to win the gold medal in the 1500 metres.
• Canada initially refused to allow the Republic of China's team (Taiwan) into the country as Canada did not recognize Taiwan as a nation. Canada's decision was in violation of its agreement with the IOC to allow all recognized teams. Canada agreed to allow the Taiwanese athletes into the country if they did not compete under the name or flag of the Republic of China. This led to protests and a threatened boycott by other countries including the US, but these came to naught after the IOC acquiesced to the Canadian demand which, in turn, led Taiwan to boycott the Games. The People's Republic of China also continued its boycott over the failure of the IOC to recognize its team as the sole representative of China.
• The various boycotts resulted in only 92 countries participating, down from 121 in 1972 and the lowest number since the 1960 Rome Games in which 80 states competed.
• Soviet modern pentathlete Boris Onishchenko was found to have used an épée which had a pushbutton on the pommel in the fencing portion of the pentathlon event. This button, when activated, would cause the electronic scoring system to register a hit whether or not the épée had actually connected with the target area of his opponent. As a result of this discovery, he and the Soviet pentathlon team were disqualified.
• Quebec, the host province, incurred $1.5 billion in debt, which was not paid off until December 2006. The Mayor of Montreal Jean Drapeau had famously said: "The Olympics can no more lose money than a man can have a baby."

1980 Summer Olympics – Moscow, Soviet Union

• 1980 Summer Olympics boycott: U.S. President Jimmy Carter instigated a boycott of the games to protest the Soviet invasion of Afghanistan, as the Games were held in Moscow, the capital of the Soviet Union. Many nations refused to participate in the Games. The exact number of boycotting nations is difficult to determine, as a total of 66 eligible countries did not participate, but some of those countries withdrew due to financial hardships, only claiming to join the boycott to avoid embarrassment. Iran also boycotted the Moscow Games owing to Ruhollah Khomeini's support for the Islamic Conference's condemnation of the invasion of Afghanistan. Only 80 countries participated in the Moscow games, fewer than the 92 that had joined the 1976 Montreal games and the lowest number since the 1960 Rome games which had also featured 80 countries. A substitute event, titled the Liberty Bell Classic, often referred to as Olympic Boycott Games, was held at the University of Pennsylvania in Philadelphia by 29 of the boycotting countries.
• A 1989 report by a committee of the Australian Senate claimed that "there is hardly a medal winner at the Moscow Games, certainly not a gold medal winner ... who is not on one sort of drug or another: usually several kinds. The Moscow Games might well have been called the Chemists' Games." A member of the IOC Medical Commission, Manfred Donike, privately ran additional tests with a new technique for identifying abnormal levels of testosterone by measuring its ratio to epitestosterone in urine. Twenty percent of the specimens he tested, including those from sixteen gold medalists would have resulted in disciplinary proceedings had the tests been official. The results of Donike's unofficial tests later convinced the IOC to add his new technique to their testing protocols. The first documented case of "blood doping" occurred at the 1980 Summer Olympics as a runner was transfused with two units of blood (i.e. two pints or about 950 ml) before winning medals in the 5,000 m and 10,000 m.
• Polish gold medallist pole vaulter Władysław Kozakiewicz showed an obscene bras d'honneur gesture in all four directions to the jeering Soviet public, causing an international scandal and almost losing his medal as a result. There were numerous incidents and accusations of Soviet officials using their authority to negate marks by opponents to the point that IAAF officials found the need to look over the officials' shoulders to try to keep the events fair. There were also accusations of opening stadium gates to advantage Soviet athletes, and causing other disturbances to opposing athletes.
• Australian triple jumper Ian Campbell was controversially fouled for scraping his foot against the ground, during a jump which would have won him the gold medal over Soviet Jaak Uudmäe. In 2015, the Australian Olympic Committee demanded an investigation into the results.

1984 Summer Olympics – Los Angeles, California, United States

• 1984 Summer Olympics boycott: The Soviet Union and fourteen of its allies boycotted the 1984 Games held in Los Angeles, United States, citing a lack of security for their athletes as the official reason. The decision was regarded as a response to the United States-led boycott issued against the Moscow Olympics four years earlier. The Eastern Bloc organized its own event, the Friendship Games, instead. The fact that Romania, a Warsaw Pact country, opted to compete despite Soviet demands led to a warm reception of the Romanian team by the United States. When the Romanian athletes entered during the opening ceremonies, they received a standing ovation from the spectators. For different reasons, Iran and Libya also boycotted the Games.
• The men's light heavyweight boxing match between Kevin Barry and Evander Holyfield ended in controversy, when referee Grigorije Novičić of Yugoslavia disqualified a clearly dominant Holyfield. Barry eventually won the silver medal, with Holyfield settling for bronze.
• In the women's 4 × 400-meter relay, injured Puerto Rican runner Madeline de Jesus enlisted her identical twin sister, Margaret, as an imposter for a qualifying heat. Margaret ran the second leg of the qualifier, and the team advanced but when the chief coach of the Puerto Rican team learned of the ruse, he pulled his team out of the final.
• In the women's 3000 meters, American Mary Decker and South African Zola Budd (representing Great Britain) infamously collided, leaving Decker injured and unable to continue. Budd was initially disqualified from her 7th place finish but was later reinstated.
• One third of the United States cycling team was found to have received blood doping.

1988 Summer Olympics – Seoul, Republic of Korea

• The games were boycotted by North Korea and its ally, Cuba. Ethiopia, Albania and the Seychelles did not respond to the invitations sent by the IOC. Nicaragua did not participate due to athletic and financial considerations. The participation of Madagascar had been expected, and their team was expected at the opening ceremony of 160 nations but the country withdrew because of financial reasons.
• Canadian sprinter Ben Johnson was stripped of his gold medal for the 100 metres when he tested positive for stanozolol after the event.
• In a highly controversial 3–2 judge's decision, South Korean boxer Park Si-Hun defeated American Roy Jones Jr., despite Jones pummelling Park for three rounds, landing 86 punches to Park's 32. Allegedly, Park himself apologized to Jones afterward. One judge shortly thereafter admitted the decision was a mistake, and all three judges voting against Jones were eventually suspended. The official IOC investigation concluding in 1997 found that three of the judges had been wined and dined by South Korean officials. This led to calls for Jones to be awarded a gold medal, but the IOC still officially stands by the decision, despite the allegations.
• American diver Greg Louganis suffered a concussion after he struck his head on the springboard during the preliminary rounds. He completed the preliminaries despite his injury, earning the highest single score of the qualifying round for his next dive and repeated the dive during the finals, earning the gold medal by a margin of 25 points. Louganis had been diagnosed HIV-positive six months prior to the games—a diagnosis that was not publicly disclosed until 1995. This led some to question Louganis' decision not to disclose his HIV status during the Games, although blood in a pool posed no risk.

1992 Summer Olympics – Barcelona, Catalonia, Spain

• Three British athletes, sprinter Jason Livingston, weightlifters Andrew Davies and Andrew Saxton, were sent home after being tested positive for anabolic steroids and Clenbuterol.
• Russian weightlifter Ibragim Samadov was disqualified for a protest after he refused to accept the bronze medal at the medal ceremony. He was eventually banned for life.
• In the final of the men's 10,000 m Moroccan Khalid Skah was racing Kenyan Richard Chelimo for the gold medal; with three laps remaining they both lapped Moroccan Hammou Boutayeb. Although he was lapped he stayed with the leaders, slowing down the Kenyan and inciting the crowd to jeer. Initially Skah was disqualified for receiving assistance from a lapped runner, but, after an appeal by the Moroccan team to the IAAF, he was reinstated and his gold medal stood.
• Yugoslavia had to compete under the Independent Olympic Participants label and were banned from team events due to the country's conduct in the Yugoslav Wars and United Nations sanctions.

1996 Summer Olympics – Atlanta, Georgia, USA

• The 1996 Olympics were marred by the Centennial Olympic Park bombing.
• A gold medal boxing match in which Daniel Petrov from Bulgaria won against Mansueto Velasco from the Philippines was described as robbery in the Philippines. One media outlet claimed that it appeared that the judges were pressing the buttons on their electronic scoring equipment for the wrong boxer. However, neutral commentators stated that "[i]n Atlanta [Petrov] proved his supremacy beyond doubt and was never really troubled in any of his 4 fights" and that "Velasco’s attempt to be the Philippines' first Olympic champion faltered from the beginning and [Petrov] was a clear winner by 19 points to 6". The New York Times reported that "Daniel Petrov Bojilov ... dominated Mansueto Velasco of the Philippines, 19-6", but acknowledged that "the Filipino deserved more points".

2000 Summer Olympics – Sydney, Australia

• In December 2007, American track star Marion Jones was stripped of five medals after admitting to anabolic steroid use. Jones had won three gold medals (100-metre sprint, 200-metre sprint and 4x400 relay) and two bronze medals (long jump and 4x100 relay). The IOC action also officially disqualified Jones from her fifth-place finish in the Long Jump at the 2004 Summer Olympics. At the time of her admission and subsequent guilty plea, Jones was one of the most famous athletes to be linked to the BALCO scandal. The case against BALCO covered more than 20 top level athletes, including Jones's ex-husband, shot putter C.J. Hunter, and 100 m sprinter Tim Montgomery, the father of Jones' first child.
• Lance Armstrong: see History of Lance Armstrong doping allegations see Lance Armstrong doping case On January 17, 2013, the International Olympic Committee removed Armstrong's results in the 2000 Summer Olympics from its record books, and requested the return of his bronze medal from the time trial.
• In the Women's artistic gymnastics, Australian competitor Allana Slater complained that the vault was set too low. The vault was measured and found to be 5 centimetres lower than it should have been. A number of the gymnasts made unusual errors, including American Elise Ray, who missed the vault completely in her warm-up, and Briton Annika Reeder, who fell and had to be carried off the mat after being injured.
• Romanian Andreea Răducan became the first gymnast to be stripped of a medal after testing positive for pseudoephedrine, at the time a prohibited substance. Răducan, 16, took Nurofen, a common over-the-counter medicine, to help treat a fever. The Romanian team doctor who gave her the medication was expelled from the Games and suspended for four years. The gold medal was finally awarded to Răducan's teammate Simona Amânar. Răducan was allowed to keep her other medals, a gold from the team competition and a silver from the vault.
• Chinese gymnast Dong Fangxiao was stripped of a bronze medal in April 2010. Investigations by the sport's governing body (FIG) found that she was only 14 at the 2000 Games. (To be eligible the gymnastic athletes must turn 16 during the Olympic year). FIG recommended the IOC take the medal back as her scores aided China in winning the team bronze. The US women's team, who had come fourth in the event, moved up to third.

2004 Summer Olympics – Athens, Greece

• In artistic gymnastics, judging errors and miscalculation of points in two of the three events led to a revision of the gymnastics Code of Points. The South Korean team contested Tae-Young's parallel bars score after judges misidentified one of the elements of his routine. Further problems occurred in the men's horizontal bar competition. After performing a routine with six release skills in the high bar event final (including four in a row—three variations of Tkatchev releases and a Gienger), the judges posted a score of 9.725, placing Nemov in third position with several athletes still to compete. The crowd became unruly on seeing the results and interrupted the competition for almost fifteen minutes. Influenced by the crowd's fierce reaction, the judges reevaluated the routine and inflated Nemov's score to 9.762.
• While leading in the men's marathon with less than 10 kilometres to go, Brazilian runner Vanderlei de Lima was attacked by de-frocked Irish priest Neil Horan and dragged into the crowd. De Lima recovered to take bronze, and was later awarded the Pierre de Coubertin medal for sportsmanship.
• Hungarian fencing official Joszef Hidasi was suspended for two years by the FIE after committing six errors in favour of Italy during the gold-medal match in men's team foil, denying the Chinese opponent the gold medal.
• Canadian men's rowing pair Chris Jarvis and David Calder were disqualified in the semi-final round after they crossed into the lane belonging to the South African team, interfering with their progress. The Canadians appealed unsuccessfully to the Court of Arbitration for Sport.
• In the women's 100 m hurdles, Canadian sprinter Perdita Felicien stepped on the first hurdle, tumbling to the ground and taking Russian Irina Shevchenko with her. The Russian team filed an unsuccessful protest, pushing the medal ceremony back a day. Track officials debated for about two hours before rejecting the Russian arguments. The race was won by the United States' Joanna Hayes in Olympic-record time.
• Iranian judoka Arash Miresmaili was disqualified after he was found to be overweight before a judo bout against Israeli Ehud Vaks. He had gone on an eating binge the night before in a protest against the IOC's recognition of the state of Israel. It was reported that Iranian Olympic team chairman Nassrollah Sajadi had suggested that the Iranian government should give him $115,000 (the amount he would have received if he had won the gold medal) as a reward for his actions. Then-President of Iran, Mohammad Khatami, who was reported to have said that Arash's refusal to fight the Israeli would be "recorded in the history of Iranian glories", stated that the nation considered him to be "the champion of the 2004 Olympic Games".
• Pelle Svensson, a former two-time world champion (Greco-Roman 100 kg class) and member of board of FILA from 1990 to 2007, has described FILA as an inherently corrupt organization. During the Games, Svensson served as chairman of the disciplinary committee of FILA. As he was watching the final in the men's Greco-Roman wrestling 84 kg class between Alexei Michine from Russia and Ara Abrahamian from Sweden, Svensson witnessed how the Russian team leader Mikhail Mamiashvili was giving signs to the referee. When Svensson approached the official and informed him that this was not allowed according to the rules, Mamiashvili responded by saying, "you should know that this may lead to your death." Svensson later found proof that the Romanian referee was bribed (according to Svensson the referee had received over one million Swedish krona).

2008 Summer Olympics – Beijing, China

Main article: Concerns and controversies at the 2008 Summer Olympics

• Players for the Spanish men's basketball teams posed for a pre-Olympic newspaper advertisement in popular Spanish daily Marca, in which they were pictured pulling back the skin on either side of their eyes, narrowing them in order to mimic the stereotypes of thin Asian eyes.
• Swedish wrestler Ara Abrahamian placed his bronze medal onto the floor immediately after it was placed around his neck in protest at his loss to Italian Andrea Minguzzi in the semifinals of the men's 84 kg Greco-Roman wrestling event. He was subsequently disqualified by the IOC, although his bronze medal was not awarded to Chinese wrestler Ma Sanyi, who finished fifth.
