LONDON -- The International Olympic Committee has disqualified a gold medalist from the London Games after she was caught doping.
Nadzeya Ostapchuk of Belarus placed first in women's shot put at the 2012 Olympics. She completed urine tests before and after competing. Both samples tested positive for metenolone, a banned substance, the IOC said in a statement released Monday.
The IOC disciplinary committee disqualified Ostapchuk from the Games, stripped her of her medal and cancelled her Olympic Identity and Accreditation Card, the statement says.
The organization also reallocated the medals for women's shot put. Original silver medalist Valerie Adams of New Zealand is now the gold medalist, bronze medalist Evgeniia Kolodko of Russia receives the silver and fourth-place finisher Lijiao Gong of China earns the bronze.
