Alberto León, a former mountain bike racer who was recently named in connection with the Spanish doping investigation known as Operación Galgo (Greyhound), has been found dead at his home.
León was found hanged in his apartment in San Lorenzo de El Escorial, near Madrid yesterday. Initial reports suggest he committed suicide.
He was one of 14 people arrested in Operation Greyhound, an investigation launched last year by Spanish police into a group who appeared to be aiding elite athletes who wanted to dope.
León was also connected with the 2006 Operación Puerto crackdown but wasn't prosecuted because there were no laws against doping in Spain at that time. He allegedly worked as a courier for Eufemiano Fuentes, the man at the centre of both cases, and provided doping products to athletes.
Police uncovered bags of blood stored in the refrigerator in León's apartment during a raid on 9 December 2010. They accused him of public health offences and trafficking in illegal substances.
Among the others accused in Operation Greyhound are world steeplechase champion Marta Dominguez and her coach Cesar Perez, athlete Alberto Garcia, fitness trainer Manuel Pascua Piqueras and agent Jose Alonso Valero. Greyhound is the third recent police investigation into doping in Spanish sports after Operation Puerto and Operation Grial, carried out in 2009.
