Armstrong is now under federal investigation and may be facing years in prison for conspiracy among other crimes.
Federal investigators are in the midst of an active criminal investigation of disgraced former Tour de France champion Lance Armstrong, ABC News has learned.
The revelation comes in stark contrast to statements made by the U.S. Attorney for Southern California, Andre Birotte, who addressed his own criminal inquiry of Armstrong for the first time publicly on Tuesday. Birotte's office spent nearly two years investigating Armstrong for crimes reportedly including drug distribution, fraud and conspiracy -- only to suddenly drop the case on the Friday before the Super Bowl last year.
Sources at the time said that agents had recommended an indictment and could not understand why the case was suddenly dropped.
Today, a high level source told ABC News, "Birotte does not speak for the federal government as a whole."
According to the source, who agreed to speak on the condition that his name and position were not used because of the sensitivity of the matter, "Agents are actively investigating Armstrong for obstruction, witness tampering and intimidation."
