Tokyo: The IOC said it is "as confident as it can be" in anti-doping measures after Nigerian sprinter Blessing Okagbare was provisionally suspended for doping Saturday, hours before the former world championships silver medalist was due to run in the semifinals of the women's 100 meters at the Olympics.
"I think the ITA (International Testing Agency) and WADA (World Anti-Doping Agency) are doing a good job, and I think also what's important is it's now independent, that it is independent of us", IOC spokesman Mark Adam told journalists in Tokyo.
"Will we catch absolutely everyone? I think no one could ever say that", Adams added.
Okagbare tested positive for human growth hormone in an out-of-competition test on July 19, four days before the Olympics opened, the Athletics Integrity Unit said, prompting a mandatory provisional suspension.
The results of that test were only received by track and field's anti-doping body late Friday and after Okagbare had already run in the 100 heats on the opening day of track competition at the Olympic Stadium in Tokyo, the AIU (Athletic Integrity Unit) said.
