David Millar has been placed under formal investigation after a two-hour interview with judge RicharDavid Millar's French lawyer announced on Thursday afternoon that the British rider is being formally investigated for "possession of dangerous substances" by Nanterre-based prosecutor Richard Pallain. According to Millar's lawyer, Paul-Albert Iwens, the world time trial champion was questioned by Pallain for two hours on Thursday. "David Millar confirmed the facts he confessed to when he was taken into custody," Iwens told AFP. Millar is alleged to have confessed to using EPO. Millar was taken into custody by police on June 22 when dining with friends in Biarritz. Police are alleged to have found two empty syringes said to have contained Eprex, the most popular brand of EPO. Millar's team-mate Cdric Vasseur, who also missed out on selection for the Tour because of his involvement in the same Nanterre inquiry, has received some consolation by being selected to ride in Cofidis' team at the Tour du Doubs on Sunday. Cofidis PR Alexandre Michaud said of the decision to select Vasseur, "we are sticking to our belief in the presumed innocence of Cdric Vasseur." Like Millar, Italian Danilo Di Luca had been told he would not be allowed to start the Tour de France because of his involvement in a doping inquiry. Despite threats to turn up anyway, Di Luca's Saeco team have announced that his Tour spot will be taken by Swiss new pro David Loosli, thereby avoiding a clash with Tour boss Jean-Marie Leblanc.
