The Olympic cycling champion Tyler Hamilton, who was allowed to keep his Athens gold medal despite failing a doping test, has confessed to cheating and accused other top cyclists, including Lance Armstrong, of doing the same.
In a CBS television interview to be aired in the United States on Monday, Hamilton, after years of denials has finally admitted using performance-enhancing drugs, including EPO, and insists he's not alone.
He says he witnessed his former team mate Armstrong inject himself with the blood-booster ahead of the 1999 Tour de France, which Armstrong won.
Lance Armstrong, who won the Tour de France seven times, has always denied taking banned substances and his lawyer says Hamilton's claims are untrue.
