(dpa) - North Korea's Kim Jong Su became the first athlete to lose an Olympic medal for doping when the International Olympic Committee (IOC) announced Friday that he had been disqualified for failing a dope test.
Kim won bronze in the men's 10-metre air pistol last Saturday and followed that up with a silver in the 50m pistol on Tuesday but loses both after testing positive for the beta-blocker propranolol.
"He has been excluded from the Games and disqualified," IOC communications director Giselle Davies said, following Friday's IOC Executive Board meeting on the issue.
Jong's disqualification means Tan Zongliang of China takes silver in the 50m and Russia's Vladimir Isakov is promoted to bronze.
In the 10m air pistol, American Jason Turner now takes bronze.
Vietnamese gymnast Do Thi Ngan Thuong, who finished 59th in qualifying for the women's all-around gymnastics, also failed a dope test and was disqualified but World Anti-Doping Agency vice- president, Professor Arne Ljungqvist, said this was more likely due to error.
"This is probably a result of poor information given to the athlete involved," he said.
