Paris, France (CNN) -- A French judge has issued an arrest warrant for U.S. cyclist Floyd Landis for allegedly hacking into the computer system of the French anti-doping agency's laboratory, the agency's president said Tuesday. Investigating Judge Thomas Cassuto issued the warrant January 28 for the alleged hacking of the lab's computer system in 2006, said Marie-Christine Daubigney, the assistant prosecutor of the tribunal in Nanterre, near Paris. It was not immediately clear why the judge was issuing the warrant after more than three years. Landis, 34, was stripped of his 2006 Tour de France win and suspended from cycling for two years after he tested positive for synthetic testosterone, a banned male sex hormone.
