U.S. federal investigators looking into alleged widespread doping on Lance Armstrong’s United States Postal Service cycling team met with officials from France’s anti-doping agency AFLD this week in a move that signals the increasingly global focus of the probe, The Wall Street Journal informs. According to people familiar with the matter, the meetings took place Tuesday in Lyon at the headquarters of international police organization Interpol, which has vowed to give U.S. investigators a helping hand in the matter. The U.S. team of investigators included the Food and Drug Administration’s Jeff Novitzky, federal prosecutor Doug Miller and United States Anti-Doping Agency head Travis Tygart. These investigators questioned AFLD officials about information they have about Mr. Armstrong, who underwent scores of anti-doping tests conducted by the AFLD when he took part in the Tour de France, these people said. Messrs. Novitzky, Miller and Tygart could not be reached for comment.
