Carlos Barredo under investigation for doping

Cycling's governing body UCI have revealed that Spanish rider Carlos Barredo is currently under investigation for doping.

The world's cycling teams have begun to crack down on cyclists taking performance-enhancing drugs following the damning evidence presented against Lance Armstrong by the United States Anti-Doping Agency.

The UCI have confirmed that Barredo, who competes for Rabobank, is under investigation following a change in the rider's blood profile during the biological passport doping programme.

The programme monitors a cyclist's blood profile over a certain period of the time to check that there have been no signs of doping.
