Commonwealth Games women's 100 meters champion Osayomi Oludamola of Nigeria has tested positive for doping, the first positive case in the Games.
Oludamola, who finished second in the race but got the gold after Sally Pearson of Australia was disqualified for a false start, tested positive for the banned stimulant Methylexanemine, Commonwealth Games Federation President Mike Fennell said on Monday.
"Any positive test, whether it is in a high-profile event or not, is something that is very much regretted for a clean games, clean sport and a clean competition," Fennell said.
"One doesn't know what kind of damage will occur as the result of this test but we just want to let everyone know that we are very vigilant and the testing and laboratory analysis is of the highest standards."
Fennell said Oludamola has been notified of the result and has requested the testing of the "B" sample.
A Federal Court hearing involving Fennell, lawyers and World Anti-Doping Agency observers was held later Monday, the AP said.
Oludamola also ran in the semifinals of the 200 on Sunday, but failed to advance after finishing fourth in her heat with a time of 23.95 seconds.
