Tyler Hamilton, who was allowed to keep his Athens Olympics gold medal despite failing a doping test, has confessed to cheating and accused other top cyclists, including Lance Armstrong, of doing the same.
In an interview to be aired by "60 Minutes" on Sunday, Hamilton, after years of denials, finally admitted using performance-enhancing drugs, including EPO, and insisted he was not alone.
He said he witnessed his former team mate Armstrong inject himself with the blood-booster during the 1999 Tour de France, which Armstrong won.
"(Armstrong) took what we all took ... there was EPO ... testosterone ... a blood transfusion," Hamilton said in an excerpt released by the CBS television network.
"I saw (EPO) in his refrigerator. I saw him inject it more than one time, like we all did, like I did many, many times."
Armstrong, who won the Tour de France seven times, has always denied taking banned substances but has repeatedly had to fend off accusations despite never having failed a drugs test.
His lawyer, Mark Fabiani, said yesterday that Hamilton's accusations about Armstrong were untrue.
"Hamilton is actively seeking to make money by writing a book and now he has completely changed the story he has always told before so that he could get himself on 60 Minutes and increase his chances with publishers," Fabiani said.
"But greed and a hunger for publicity cannot change the facts: Lance Armstrong is the most tested athlete in the history of sports. He has passed nearly 500 tests over twenty years of competition."
