MOSCOW, November 12 (RAPSI) - Marsial Sogi, the head of an anti-doping laboratory in Lausanne, implicated in the scandal with the destruction of the doping tests of Russian athletes, claimed that in 2009 he received threats from Russia, R-Sport reports on Thursday.

Sogi claimed that he could prove the use of doping by Russian athletes.

On November 9 World Anti-Doping Agency (WADA) held press-conference in Geneva where independent commission of the organization accused Russia of numerous anti-doping rules violations. Commission recommended International Association of Athletics Federations (IAAF) to suspend Russian athletes from participation in competitions under its auspices, including the 2016 Olympics.

According to WADA’s commission, the head of Moscow's anti-doping laboratory Gregory Rodchenkov destroyed 1417 doping tests three days before WADA could test them. 67 samples sent from Moscow to the laboratory in Lausanne were also destroyed despite the opposition of WADA.

Sogi claimed that suspicious doping tests first appeared in 2007 while letter with threats from Russia was received two years later.
