French super heavyweight Mourad Aliev remained seated at ringside for nearly an hour after being disqualified in his Olympic boxing quarter-final, a call he furiously protested with kicks in the air and offensive gestures.

When the referee stopped his bout against Britain's Frazer Clarke with four seconds left in the second round, the Frenchman flew into a rage, spat out his mouth guard, kicked it, and punched at a TV camera.

Clarke suffered cuts above his eyes in what the referee appeared to deem an intentional headbutt by Aliev.

Aliev remained sitting at ring-side for about half an hour, then departed the arena after a word with a group of suited officials, only to return about 15 minutes later.

The quarter-final match, which ended in the second round, secured at least a bronze for Clarke.

The Englishman, who sustained a cut around his left eye, said: "I felt there was a couple of heads going in but whether it's intentional or not I don’t know.

"I’m not going to stand here and say he did it on purpose because I’m sure he wouldn’t have wanted his Olympics to end in the way they have.

"I told him to calm down because I’ve been in those situations before. The last thing I want him to do is damage his reputation or be rude to the judges and officials, because they are only doing their job."
