GENEVA — Members of Russia’s secret service intimidated workers at a drug-testing lab that analyzed samples from top athletes, persuading them to cover up positive tests. They impersonated lab engineers during the Winter Olympics in Sochi last year and kept the facility under close surveillance. That lab once destroyed more than 1,400 samples, fearing the discovery of doping violations.
Athletes, meanwhile, adopted false identities while traveling to avoid unexpected testing, and some who tested positive paid part of their prize money to make doping violations disappear. Others proactively bribed antidoping authorities to assure favorable results, and some of the country’s sports officials routinely submitted bogus urine samples for athletes who were doping.
