London: Kim Jae-bum of South Korea won the Olympic gold medal on Tuesday in the men's 81-kilogram category.
Kim defeated Ole Bischof of Germany in the final. Kim threw Bischof twice and was often on the attack, even when both were locked in grappling techniques on the floor.
The 27-year-old Kim won a silver at the Beijing Games and is the current world champion.
The bronze medals were won by Ivan Nifontov of Russia and Antoine Valois-Fortier of Canada.
