Paris:Olympic bronze medalist Naman Keita of France had "abnormal" results on an anti-doping test during the athletics World Championships, anti-doping officials said on Tuesday.
"We are not at the point of a positive result," an official from the IAAF's anti-doping department said.
That person requested anonymity, because an investigation into the matter is ongoing. "There is an abnormal result." The official said Keita had been asked to provide documents to explain the result.
In a statement, the French athletics federation said Keita confirmed "he had been advised to take a dietary supplement to help him regenerate muscle, which he then bought on the Internet." The statement did not identify the dietary supplement.
French athletics federation president Bernard Amsalem was "very disappointed" and "wanted to underscore once again how essential it is that athletes do not take advice from just anyone," the statement said. "No product or dietary supplement should be taken without checking with the federation's doctors."
Keita, third in the 400-meter hurdles at the 2004 Athens Olympics, was eliminated in the semifinals at the World Championships in Osaka, Japan last week.
IAAF president Lamine Diack announced Sunday at a news conference on the last day of the Osaka meet that a doping test had come back with "suspicious" results. It was the only case announced during the championships.
At the 2005 worlds, two athletes had their performances annulled - hammer thrower Vladislav Piskunov of Ukraine and discus thrower Neelam Jaswant Singh of India.
A total of 1,060 doping tests, 510 blood tests and 550 urine, were conducted on 926 athletes at Osaka.
