Teddy Riner of France won the men's over-100kg Olympic judo gold medal on Friday, giving him the only medal he was missing.
Riner, 23, defeated Russia's Alexander Mikhaylin in an anti-climactic final where he was mainly on the attack.
With a record five world championship titles, Riner is judo's biggest star. He won a bronze at Beijing. On Friday, Riner used both throwing and grappling techniques to win his early fights with several match-ending ippon scores.
The bronze medals were won by Germany's Andreas Toelzer and Brazil's Rafael Silva.
