London: The International Olympic Committee opened an investigation on Thursday into the Italian race walker expelled from the London Olympics for doping and could retest the 2008 gold medalist's samples from Beijing.
Two Olympic officials familiar with the case told The Associated Press that the IOC launched a disciplinary case against Alex Schwazer. He was removed from the team by the Italian Olympic Committee on Monday after testing positive for endurance-enhancing EPO in a pre-competition doping control.
The officials spoke on condition of anonymity because the investigation hasn't been officially announced.
Schwazer, who won the 50-kilometer race walk at the 2008 Beijing Games, has insisted he was clean at the time.
A three-person International Olympic Committee disciplinary panel is now looking into the case and considering whether to retest his Beijing samples for any banned substances.
