Moscow - Russian federal investigators said on Friday they had
sent the World Anti-Doping Agency "proof" refuting claims by whistleblower
Grigory Rodchenkov of a state-sponsored doping programme at the Sochi Olympics
"The investigators have collected objective proof
refuting Rodchenkov's deceitful evidence concerning the delivery of athletes'
doping samples to the Sochi anti-doping laboratory," the Russian
Investigations Committee said in a statement.
The committee said it had sent WADA documents relating to
the registration of doping samples that contradicted the whistleblower's
allegations, according to the statement on its website.
The body, which reports directly to the Kremlin, opened an
investigation into the scandal in 2016.
Former Russian Anti-Doping Agency chief Rodchenkov provided
key evidence leading to suspensions of Russian athletes from global sport, including
a ban from competing under the Russian flag at February's Pyeongchang Winter
The suspensions followed revelations based on Rodchenko's
evidence concerning a vast state-sponsored doping scheme that included charges
that tainted urine samples were switched with clean ones at the Sochi Games.
Rodchenkov fled to the United States in late 2015 and went
into hiding, saying that Russian President Vladimir Putin wanted him dead for
his role in exposing the doping conspiracy.
