Double Olympic champion Yuri Alvear of Colombia clinched International Judo Federation (IJF) Grand Slam gold with victory against German Giovanna Scoccimarro in Brasilia.

The triumph gives Alvear just a second Grand Slam win as Montreal Grand Prix winner Scoccimarro took silver at Centro Internacional de Convenções do Brasil.

Britain's Gemma Howell will move into the IJF top 10 after she claimed bronze, when world number 12 Assmaa Niang of Morocco was penalised for going out of the area three times.

Livesey secured a medal against Brazil's Mariana Silva with an ura-nage throw for ippon.

In the men's under-73kg contest, Musa Mogushkov of Russia won a fourth Grand Slam gold against unfancied Brazilian David Lima.

Mogushkov needed just 36 seconds to floor the world number 76 with a tai-otoshi.

Japan's Soichi Hashimoto earned bronze by defeating Giovanni Esposito of Italy.

The second bronze went to German Anthony Zingg, who overcame Nils Stump from Switzerland with a uchi-mata throw for a waza-ari score.
