US federal agents are investigating disgraced former Tour de France champion Lance Armstrong for crimes including obstruction, witness tampering and intimidation, ABC News reported on Wednesday.
Citing an anonymous source, ABC News said the current probe is focused on different charges from those previously investigated in a federal probe that was dropped last year.
US Attorney Andre Birotte said he had no plans to press charges despite Armstrong's recent doping admissions, but he did not definitively rule out such action. Birotte's investigation was centered on doping, fraud, conspiracy and Armstrong's denials of such crimes when he was the lead rider in the extremely successful government-funded US Postal Service Team.
The ABC News source, quoted on condition of anonymity, said: "Birotte does not speak for the federal government as a whole. Agents are actively investigating Armstrong for obstruction, witness tampering and intimidation."
USADA wants lance 'to be part of solution'
Los Angeles: US Anti-Doping Agency chief Travis Tygart said Wednesday that Lance Armstrong wants to help clean up cycling, and the agency has extended the deadline for the confessed cheat to cooperate with it.
"We have been in communication with Mr. Armstrong and his representatives and we understand that he does want to be part of the solution and assist in the effort to clean up the sport of cycling," Tygart said in a statement.
"We have agreed to his request for an additional two weeks to work on details to hopefully allow for this to happen."
