The agency's president, Pierre Bordry, told cyclingnews.com the warrant was issued Jan. 28. A trace of a November 2006 hacking incident on the agency's computer was allegedly linked to Landis's coach, Arnie Baker.
Landis finished first at the 2006 Tour de France but had the title stripped after he was found to have had abnormally high levels of testosterone in his system. The lab that completed tests on samples from Landis was the target of a hacking attack.
The cyclist overcame a large time deficit in Stage 17 of the 200 Tour de France to take the overall lead. It was from samples taken after that stage that the elevated levels of testosterone were found. Landis was banned from competition for two years, a ban that ended in January 2009.
Landis denied the doping allegations but the American Arbitration Association and the Court for Arbitration for Sport both upheld the decision.
