LAUSANNE - Shamed former IAAF president Lamine Diack has resigned from his position on the International Olympic Committee, where he had served as an honorary member, the IOC said Wednesday. The 82-year-old Diack, who is being probed over corruption charges, "has resigned from his position as an honorary member of the IOC," said IOC presidency spokesman Mark Adams in an email sent to AFP. Diack had been provisionally suspended by the IOC on Tuesday evening. He became an honorary member of the committee in 2013. The Senegalese national served as head of the International Association of Athletics Federations for 16 years until August. He was arrested by French investigators and charged with corruption last week amid allegations he took bribes to cover up doping cases, principally in Russia.
