Dusseldorf: The world athletics governing body IAAF has referred allegations made about systematic doping in Russian sport to an independent ethics committee, the organization confirmed to dpa Thursday. On Wednesday the German state broadcaster ARD ran a documentary, ‘Top secret doping - how Russia makes its winners’, which included secretly filmed meetings as well as statements from two whistleblowers - a former employee of the Russian Anti-Doping Agency (RUSADA), Vitaliy Stepanov, and his wife, Yuliya Stepanova, a middle distance runner currently banned over substance abuse. ARD alleged Russian sport is plagued by systematic doping, covering up of tests and corruption.
