Three Russian biathletes have sued the country's former anti-doping laboratory director, saying he severely damaged or destroyed their careers with lies.
The athletes filed a $US30 million ($A38 million) libel lawsuit Tuesday in Manhattan State Supreme Court against Dr Grigory Rodchenkov, who lives in hiding in the US.
Rodchenkov has denied claims by Russian President Vladimir Putin that US agencies controlled his unmasking of the scandal.
Just days ago, Rodchenkov told AP in response to questions sent through his lawyer he fears for his life after producing documents describing an elaborate ruse by Russian athletes to evade doping tests.
The lawsuit says Rodchenkov's false allegations "ultimately warped history and stripped the athletes of the life-long accomplishments they had earned."
