LONDON – Just hours after the close of the Olympics, a female shot putter from Belarus was stripped of her gold Monday in the first case of an athlete losing a medal for doping at the London Games.

With the disqualification of Nadzeya Ostapchuk, the gold medal was awarded to Valerie Adams of New Zealand – who winds up as Olympic champion for the second time in a row.

The International Olympic Committee said Ostapchuk, a former world champion, tested positive for steroids both before and after winning the shot put last week for her first Olympic gold.
