World time trial champion David Millar was formally placed under judicial investigation on Thursday for illegal possession of toxic products, his lawyer said.
Millar told a court west of Paris that he had used the banned blood booster Erythropoietin (EPO), a fact he had already revealed during 48 hours of police custody last week, lawyer Paul-Albert Iwens said.
The 27-year-old rider was released with no restrictions on his freedom of movement, Iwens said.
Millar was detained last week over allegations he had used EPO, and was subsequently barred from racing in the Tour de France which starts on Saturday.
He was second to Australian Bradley McGee in last year’s Tour prologue. Millar’s Cofidis team has been under investigation since January when seven riders and staff were charged with doping offenses.
Millar, who has never failed a drugs test, had originally denied the accusations, but admitted to doping after police found several empty EPO vials in his apartment.
The Scot might now be dropped by the British Olympic team for Athens where he had hoped to race in both the road race and time trial and in the individual pursuit on the track.
