A man who lost his cool during TV game show dashed a female fellow contestant to the floor before smacking her in the face in a sudden and unpleasant outburst.

The bikini-clad victim was left bleeding and sobbing after the sudden attack, which was filmed as part of a television programme broadcast across Russia.

The abruptness of the attack appears shocking, but commenters on the video uploaded to YouTube who have apparently watched the entire programme say was provocation leading to the attack.
