Tokyo: The Olympics have been hit with a major doping scandal after the Nigeria sprinter Blessing Okagbare tested positive for a banned substance and was ruled out of the Games just hours before she was due to race Great Britain’s Dina Asher-Smith in the 100m semi-final.
Okagbare’s suspension is the first doping case of the Tokyo games track and field competition, officials said on Saturday, reports AFP.
Former Commonwealth Games gold medallist Okagbare, 32, won her heat in 11.05sec on Friday.
Okagbare's suspension is the latest twist in a troubled track and field campaign at the Olympics for Nigeria.
On Thursday, the AIU said 10 Nigerian athletes were among 18 competitors prevented from entering competition in Tokyo after failing to meet requirements for out-of-competition testing.
Elsewhere, Kenyan sprinter Mark Odhiambo, who was to have lined up for the heats of the men's Olympic 100 metres on Saturday, has been suspended after testing positive for steroids, officials said.
"The athlete... has been informed of the case and has been provisionally suspended until the resolution of the matter in line with World Anti-Doping Code and the IOC Anti-Doping Rules," the International Testing Agency (ITA) said in a statement.
