New | Nine athletes, including six medalists, caught for doping in Beijing Games

Nine more athletes, including six medal winners, were retroactively disqualified from the 2008 Beijing Olympics on Wednesday after failing retests of their doping samples.

The International Olympic Committee announced the decisions in the latest sanctions imposed on athletes whose stored samples came back positive after being retested with improved methods.

Four athletes were stripped of silver medals and two of bronze medals in weightlifting, wrestling and women’s steeplechase. All six athletes come from former Soviet countries — Russia, Belarus, Ukraine, Uzbekistan and Kazakhstan — and all tested positive for steroids.

The IOC stores doping samples for 10 years to allow them to be reanalysed when enhanced techniques become available. The IOC recorded a total of 98 positive cases in recent resting of samples from Beijing and the 2012 London Olympics.

Stripped of silver medals Wednesday were freestyle wrestlers Soslan Tigiev of Uzbekistan (66-74 kilogram division) and Taimuraz Tigiyev of Kazakhstan (84-96 kg) and weightlifters Olha Korobka of Ukraine (75 kg) and Andrei Rybakov of Belarus (85 kg).
