The International Olympic Committee has disqualified 4 Russian athletes who participated in the 2012 London Olympics after re-tests of their samples came back positive for banned substances.
The disqualification means they are stripped of their London Olympics’ records.
More than 100 athletes have also tested positive in re-tests of their samples taken during the London and Beijing 2008 Olympics.
Russia saw virtually its entire track and field team banned from the 2016 Olympics in Rio as a result of a widespread national doping scandal that implicated sports officials, coaches, doctors and more than 1,000 athletes from many sports.
