Belarus shot putter Nadzeya Ostapchuk stripped of London 2012 gold medal ... - Telegraph.co.uk

Adams, the 2008 Olympic and three-time world champion, said she was "speechless" after hearing the news.

"It is taking me some time to take this in," Adams told Kiwi television network TVNZ from her base in Switzerland.

"It is huge and I am absolutely thrilled of course. It makes me extraordinarily proud as a New Zealander.

"It is also encouraging for those athletes, like myself, who are proud to compete cleanly, that the system works and doping cheats are caught."

An IOC statement read: "The International Olympic Committee (IOC) today announced that it has disqualified, withdrawn the medal from, and excluded Belarus's Nadzeya Ostapchuk (athletics, women's shot put) from the Games of the XXX Olympiad in London.

"The athlete was first requested to provide a urine sample for a doping control on 5 August. She competed the next day in the women's shot put event, where she placed first, and was asked to provide a sample straight after her competition.

"Both samples indicated the presence of metenolone, which is classified as anabolic agent under the 2012 Prohibited List."
