Cyclist Frank Schleck Fails Doping Test
Police are questioning Tour de France star Frank Schleck after he tested positive for a banned substance, his RadioShack team said.
Schleck, who quit the race after being informed of the positive test, went voluntarily to a police station in Pau, southwest France, to co-operate with authorities, RadioShack spokesman Philippe Maertens said.
Schleck's positive test for the banned diuretic Xipamide was announced earlier by the International Cycling Union (UCI).
The RadioShack team said it had decided to withdraw the Luxembourg rider from the race, and said that the diuretic is not present in any medicine used by the team.
RadioShack said in a statement: "The reason for the presence of Xipamide in the urine sample of Mr Schleck is unclear to the team. Therefore, the team is not able to explain the adverse findings at this point."
Mr Maertens said the team is likely to ask for the "B'' sample to be analysed, which it must do within four days.
Schleck, the team's leader, was placed 12th in this year's Tour - 9 minutes, 45 seconds behind leader Britain's Bradley Wiggins.
Frank Schleck, 32, is the older brother of 2010 Tour winner Andy, who won after original victor Alberto Contador was stripped of his title for doping offences.
In last year's Tour, Andy came second overall and Frank third.
Governing body UCI said Xipamide turned up in the test conducted by the French anti-doping lab in Chatenay-Malabry, south of Paris, on a sample from Schleck taken on July 14.
RadioShack will continue to compete in the race.
Still, it was more bad news for the RadioShack squad, which was built on the remains of former teams of Lance Armstrong.
The team manager, Johan Bruyneel, has been targeted in the same US anti-doping case targeting the seven-time Tour champion Armstrong.
Mr Bruyneel opted to skip the Tour to avoid being a distraction to the race and RadioShack riders.
The case is also likely to cast new doubt on cycling's ability to root out drugs cheats despite vigorous controls put in place by the UCI and its allies in the anti-doping fight.
It is the second doping-related case to emerge at the Tour this year. Cofidis rider Remy Di Gregorio of France was arrested on the first rest day on July 10 as part of a Marseille doping probe.
