ABC News in the US reported that a new criminal investigation into Armstrong has begun, a year after a previous two-year investigation was closed with no charges brought against him.
The evidence gathered during Usada's damning report on Armstrong's cheating which led to his confession could be used in the new federal inquiry.
The ABC report said Armstrong is now being investigated for obstruction, witness tampering and intimidation. The previous federal investigation looked at Armstrong's then-alleged drug-taking and potential fraud.
However, it appears from the statements made to ABC, the investigators are now refocusing their investigation on how Armstrong bullied and intimidated associates, including taking legal action, to conceal his doping over more than a decade.
