In 2010, an employee at the Russian Anti-Doping Agency (Rusada) began sending information to the World Anti-Doping Agency (Wada) alleging that Rusada was enabling systemic doping in athletics. The unfolding revelations since have resulted in one of the biggest scandals to ever emerge in the history of the Olympic Games. In July 2016, an independent investigation commissioned by Wada reported that the Russian ministry of sport and the Federal Security Service (FSB) had operated a state-dictated system to cover up positive doping samples of its athletes. The episode resulted in a number of investigations, which have so far led to the banning of the Russian track and field team for the upcoming Rio Olympic Games as well as lifetime bans for a number of high-ranking Russian sports officials.
