Eight Russian athletes fail drugs test in re-testing of samples from 2012 Olympics in London
Eight Russian athletes failed drug tests in the re-testing of samples from the London 2012 Olympics, the Russian Olympic Committee has announced.
The ROC said in a short statement on Saturday that the athletes came from three different sports, but added they would not be named until their 'B' samples had been analysed.
Those eight Russians were among 23 athletes who returned positive tests in the re-testing of 2012 samples.
The re-analysis of samples from the 2008 Games in Beijing revealed 31 failed drug tests, 14 from Russian competitors.
The news that over a third of the positive re-tests from London 2012 belonged to Russians, on top of almost half of those from Beijing, will only increase the pressure on the International Olympic Committee to ban the country from the Rio Games in August.
Allegations of state-sponsored doping at the 2014 Winter Olympics in Sochi have also come to light.
Athletics' world governing body the IAAF has already banned Russia from international competition, after a World Anti-Doping Agency investigation revealed systematic doping among its athletes, and its ruling Council will meet on June 17 to decide whether they should be allow to compete in Brazil.
The re-tests from the 2008 and 2012 Games were targeted at athletes who could potentially participate in Rio and seem certain to lead to bans from this summer's Olympics.
The 23 positive results from London 2012 came from 265 re-tested samples, with the 31 from Beijing coming from 454 samples. The IOC has said the reanalysis programme is ongoing, with the possibility of more results in the weeks to come.
