Athletics Champion, Oluwatobiloba Amusan, has won her 100m heat at the ongoing World Athletics Championship currently taking place in Budapest, Hungary.
The 26-year-old finished with 12.48 seconds in a blistering speed.
Recall that the AIU had temporarily banned her over Whereabouts Failures charge.
The 26-year-old athlete faced charges of three whereabouts failures, which constitutes an anti-doping rule violation for missing three out-of-competition tests within a 12-month period.
Amusan contested the charge and was cleared last Friday.
The clearance provided her with the opportunity to defend the only title in her career that she has yet to defend, following her successful retention of her Nigeria, African Championships, African Games, Commonwealth Games, and Diamond League titles.
