The Athletics Integrity Unit (AIU), the independent body created by the World Athletics that manages all integrity issues for the sport, announced the decision. According to the body, Okagbare tested positive for Human Growth Hormone.

“Growth Hormone is a non-specified substance on the 2021 World Anti-Doping Agency (WADA) Prohibited List and a provisional suspension is mandatory following an adverse analytical finding for such substance under the World Athletics Anti-Doping Rules.

The AIU collected the sample from  Okagbare during an out-of-competition test on 19 July. The WADA-accredited laboratory that analyzed the sample notified the AIU of the adverse analytical finding at mid-day Central European Time yesterday, Friday 30 July.

The results of the test were only received by the track and field’s anti-doping body late Friday, 30 July, after Okagbare, who won her heat in 11.05seconds, qualified for the semifinals of women’s 100m race at the Olympics.

The athlete was notified of the adverse analytical finding and of her provisional suspension this morning in Tokyo. She was scheduled to participate in the semi-finals of the women’s 100m this evening.

The AIU will make no further comment on this matter at this time.” the AIU said in its statement.
