Italian Emmanuele Sella has tested positive for Mircera, a potent form of the blood boosting drug erythropoietin (EPO).
The 27 year-old was caught in an out of competition test conducted by the UCI, and he tested positive for the same substance as Riccardo Riccò, Manuele Beltran and Moises Duenas did during the Tour de France.
"It was targeted control," said UCI President Pat McQuaid to Cyclingnews.com. "The control was done on July 23 and we sent the samples to Paris for testing."
McQuaid noted that Sella had been targeted based on his actions in and out of racing: "It was a highly targeted out-of-competition test. We are using a range of information to target riders."
Sella's reaction was incredulous: "I know absolutely nothing of this story, no-one has communicated anything to me. It is not true at all," he was quoted by Italian newsagency Ansa as saying.
The Italian riding for the small CSF Navigare team, won three mountain stages and the green king of the mountains jersey in this year's Tour of Italy.
