Ten athletes have been stripped of medals won during the 2008 summer Olympic Games after testing positive for banned substances, the International Olympic Committee (IOC) has announced.
No gold medallists have been punished, although three silver medallists are among those to have been sanctioned following retests of samples from the Games in Beijing, China.
Russian weightlifter Khadzhimurat Akkaev, who picked up a bronze medal, has been disqualified, along with countryman Khasan Baroev, who claimed silver in the 96-120kg Greco-Roman wrestling event.
Other athletes to have been stripped of their bronze medals include Ukrainian weightlifter Natalya Davydova; Greek triple jumper Chrysopigi Devetzi; Kazakh weightlifter Mariya Grabovetskaya; Russian weightlifter Dmitry Lapikov; Kazakh wrestler Asset Mambetov and Ukrainian pole-vaulter Denys Yurchenko.
Other silver medallists to have had their medals stripped include Kazakh weightlifter Irina Nekrassova (pictured) and Azerbaijani wrestler Vitaliy Rahimov.
Six further athletes who did not pick up medals have also been retrospectively punished. They are: Belarusian weightlifter Iryna Kulesha; Kazakh weightlifters Maya Maneza and Vladimir Sedov; Ukrainian high-jumper Vita Palamar; Azerbaijani weightlifter Nizama Pashayev and Russian high-jumper Elena Slesarenko, who won gold at the 2004 Games in Athens.
The IOC said the 10 medallists had all tested positive for various steroids.
