The International Olympic Committee on Friday announced that three additional Russian track and field athletes, including sprinter Anastasiya Kapachinskaya, have been retroactively disqualified from the 2008 Beijing Olympics for testing positive for steroids in a reanalysis of doping samples.

Kapachinskaya and her Russian teammates will be stripped of the silver medal they won in the women’s 4×400-meter relay after Kapachinskaya tested positive for the prohibited substances stanozolol and turinabol. Jamaica and Belarus will be awarded the silver and bronze medals, respectively.

Friday’s sanctions are the latest levied by the IOC following a reanalysis of doping samples from the 2008 and 2012 Olympics using enhanced techniques. On Wednesday, the IOC announced that Russian sprinter Yulia Chermoshanskaya was disqualified from the 2008 Games after traces of two banned substances were found in her Beijing samples. The ruling stripped Russia of its gold medal in the 4×100-meter relay.

Alexander Pogorelov and Ivan Yushkov were the other two Russian athletes disqualified from the 2008 Games on Friday. Pogorelov, who placed fourth in the decathlon, tested positive for turinabol. Yushkov, who placed 10th in the shot put, tested positive for stanozolol, oxandrolone and turinabol.

Earlier this week, the IOC stripped Ukrainian javelin thrower Oleksandr Pyatnytsya of his silver medal from the 2012 London Games and disqualified three other athletes — weightlifters Nurcan Taylan of Turkey, Hripsime Khurshudyan of Armenia and Pavel Kryvitski of Belarus — for doping violations at the last two Olympics.

After an investigation by the World Anti-Doping Agency found Russia’s Ministry of Sport was complicit in drug cheating by hundreds of athletes, the IOC banned all but one member of the Russian track and field team from competing in Rio. Darya Klishina finished ninth in the long jump on Wednesday, leaving Russia without a track and field medal for the first time since its Summer Olympics debut in 1996.
