A French judge has issued an international warrant for Landis in connection with a case of data hacking at a doping laboratory, according to France's anti-doping chief.
Pierre Bordry told The Associated Press on Monday that French judge Thomas Cassuto is seeking to question Landis about computer hacking dating back to September 2006. Bordry says computers at the Chatenay-Malabry laboratory were breached by hackers who took data in a bid to discredit the lab.
The 34 year old Landis, who lives in Temecula, Calif., won the 2006 Tour de France but was disqualified and banned for two years when doping tests revealed abnormally high levels of testosterone. The samples were analyzed at the Chatenay-Malabry lab.
Landis's appeal over the decision was rejected by the Court of Arbitration for Sport. The Los Angeles Times reports that Bordry claims that documents Landis presented during his appeal process were taken from the lab's computers.
Landis would be arrested only if he were in France or its territories.
The French lab was conducting doping tests on Landis -- which is routine for racer -- and found he used artificial testosterone when he won the Tour de France in 2006. Landis was stripped of his victory and banned from competitive cycling for two years. He was the first person ever to be stripped of a Tour de France victory.
His two year ban ended in 2009 when he joined the OUCH Pro Cycling Team and rode the Tour of California in February.
