Landis was banned for two years after failing a drug test
A judge has issued an arrest warrant for cyclist Floyd Landis for allegedly hacking into a French anti-doping agency laboratory computer.
Landis was stripped of the 2006 Tour de France title after testing positive for excess levels of testosterone.
The warrant was originally said to apply internationally, but a French court official has since clarified that it applies only to French territory.
The alleged computer hacking is said to have taken place in September 2006.
The Court of Arbitration for Sport (CAS) rejected Landis's appeal that the positive test was caused by procedural mistakes by the French laboratory.
The 34-year-old American was banned from racing for two years, returning to action in January 2009.
