A Dallas promotions company sued Lance Armstrong on Thursday, demanding he repay $12 million in bonuses and fees it paid him for winning the Tour de France.

SCA Promotions had tried in a 2005 legal dispute over the bonuses to prove Armstrong cheated to win before it ultimately settled and paid him.

Armstrong recently acknowledged using performance-enhancing drugs after the U.S. Anti-Doping Agency in 2012 detailed a sophisticated doping program by his Armstrong's teams. Armstrong was stripped of his seven Tour de France victories and given a lifetime ban from sports.

Now, the company contends in its lawsuit, Armstrong and agent Bill Stapleton lied and conspired to cheat SCA out of millions. The lawsuit notes that Armstrong repeatedly testified under oath in the 2005 dispute that he did not use steroids, other drugs or blood doping methods to win, all of which he now admits to doing.

"It is time now for Mr. Armstrong to face the consequences of his actions," said the lawsuit, which demands a jury trial. "He admits he doped; he admits he bullied people; he admits he lied."

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."

An email to an attorney for Armstrong was not immediately returned.
