Olympics boxing: French boxer Vastine rages after defeat

Frenchman Alexis Vastine is denied victory and a place in the men's welterweight semi-finals after narrowly losing to top-seeded Taras Shelestyuk of Ukraine at the ExCel Arena.

Vastine, who was also denied a win in the Beijing semi-final four years ago, was furious at the decision, lashed out in rage, then staged a sit in.

World champion Shelestyuk will now face Great Britain's Fred Evans in the semi-finals.
