A French prosecutor has launched an investigation into allegations made about Lance Armstrong in thePICTURE BY TDWSPORT.COM According to Thursday's editions of Aujourd'hui and Le Parisien, French prosecutors have opened proceedings into alleged doping by six-time Tour de France champion Lance Armstrong. The inquiry stems from a magistrate's interview with Armstrong's former soigneur Emma O'Reilly, who was reported to have confirmed the allegations of the Texan using the banned blood-booster EPO she made in the book 'LA - Confidential - The Secrets of Lance Armstrong'. Armstrong is currently suing the authors of the book, Sunday Times journalist David Walsh and former L'Equipe journalist Pierre Ballester, for defamation. "This preliminary inquiry has only just begun and it would be premature to draw any conclusions, one way or another," the Annecy prosecutors' office told Le Parisien. The investigation was initially based in Paris, but has reportedly been transferred to Annecy because, says Le Parisien, investigators are looking into statements from a witness based in the Haute Savoie region.
