Why has Nigerian sprinter Divine Oduduru been banned for 6 years?

Nigerian sprinter Divine Oduduru has been banned for six years by the Athletics Integrity Union (AIU) for two Anti-Doping Rule Violations. The ban comes after the AIU found “overwhelming evidence” against the athlete, including the possession and attempted use of prohibited substances. Oduduru’s teammate, Blessing Okagbare, received an 11-year ban for doping and non-cooperation with the investigation.
