Former cyclist Lance Armstrong's seven Tour de France victories are in jeopardy after the U.S. Anti-Doping Agency sent him and a number of riders a letter bringing formal doping charges, reports the Washington Post.
Armstrong is also banned from competing in triathlons because of the formal charges.
The letter obtained by the Post says in part that Armstrong's blood is "fully consistent with blood manipulation including EPO use and/or blood transfusions.”
Armstrong has never tested positive for any blood doping. The letter, dated June 12, also accuses five former cycling team associates of a doping conspiracy from 1998-2011 and that more than 10 cyclists are witnesses.
Earlier this year, the U.S. Attorney's Office ended their investigation into Armstrong, which ended a two-year probe into doping allegations.
Armstrong’s former teammates Floyd Landis and Tyler Hamilton cooperated with federal agents and accused Armstrong of doping.
Armstrong’s attorney, Robert D. Luskin, called USADA’s allegations a product of “malice and spite”.Armstrong responded to the charges on his website
