The silver medalist of the Tokyo Olympics, Briton Chijindu Uja, was suspended due to suspicion of violation of anti-doping rules. It is reported on the website of the Independent Authority against Adverse Events in Athletics (AIU).
According to the source, the 27-year-old track and field athlete was found to have tested positive for the banned substances Ostarine and S-23 in a sample taken at the Tokyo Games. A disciplinary case was opened against him. It is noted that runners Alsadik Miku from Bahrain, Mark Odhiambo from Kenya, and Benik Abrahamyan from Georgia, who competes in the shot put, were also caught doping.
Ujjah won silver in the 4 by 100-meter relay. He also won the 2013 European Junior Championships.
During the Tokyo Olympics, several Belarusian and Ukrainian track and field athletes were suspended from participating in the Games. The athletes were sanctioned for failing to comply with the rule that an athlete must undergo three doping tests in the out-of-competition period within ten months.
