More than 1,000 Russian athletes in about 30 sports took part in an "institutional conspiracy" to use banned drugs at the Sochi and London Olympics and other global events, doping investigator Richard Mclaren said Friday.

McLaren, who has accused Russia of "state-sponsored" cheating, said in his new report that he had confirmed the switching of samples at the Sochi Winter Olympics in 2014 and that salt and coffee was used to manipulate samples when checked by international experts.
