The former head of Russia's Anti-Doping Agency, Nikita Kamayev, contacted a British newspaper shortly before his sudden death offering to expose the country's development of performance-enhancing drugs, London's Sunday Times reports.
The newspaper reports that 10 weeks before Kamayev allegedly died of a heart attack, he wrote an e-mail to the Sunday Times saying he wanted to write a book that would reveal the complete extent of doping in Russia.
"I want to write a book about the true story of sport pharmacology and doping in Russia since 1987 while being a young scientist working in a secret lab in the U.S.S.R. Institute of Sports Medicine," he wrote in the e-mail.
He added that he had "information and facts that have never been published."
Russia was suspended from international track and field competitions in November after a special World Anti-Doping Agency (WADA) commission issued a report that alleged widespread state-sponsored cheating and corruption.
Kamayev, who resigned as executive director of Russia's Anti-Doping Agency (RUSADA) in mid-December, died on February 14 at the age of 52.
Former RUSADA Director-General Ramil Khabriyev said he had been "told" that Kamayev "was out cross-country skiing, came home, and felt pain in the area of the heart." (Some Russian media put Kamayev's age at 50.)
RUSADA also confirmed that the agency's founding chairman, Vyacheslav Sinev, died on February 3. It did not give a cause of death. Sinev left RUSADA in 2010.
