IOC strips London Games gold from three Kazakh weightlifters in latest doping revelations
The trio test positive for the steroid stanozol and hand back their Olympic medals four years on

The International Olympic Committee on Thursday stripped three Kazakh weightlifters of gold medals won at the London 2012 Games for doping.
Zulfiya Chinshanlo, Maiya Maneza and Svetlana Podobedova were all caught in new testing of hundreds of samples from the London and 2008 Beijing Olympics.
A weightlifter from Belarus who won a bronze medal was also disqualified by the IOC.
Russian weightlifter Besik Kudokov, who won a silver in London, also failed a doping test but the medal was not taken away because he died in 2013.
Chinshanlo, now 30, Maneza, 30, and Podobedova, 29, all tested positive for the steroid stanozol. Chinshanlo was also found to have taken oxandrolone, another steroid. Both substances promote muscle growth.
