Cops search for footage of Vic pub bashing

The moment a patron was knocked unconscious during a fight with four security guards outside a Victorian pub may have been caught on camera.

The victim, 23, was ejected from the hotel in Portsea in mid-June before a fight broke out with the four security guards during which he was hit in the face and knocked unconscious, falling onto the road.

Police are searching for a man and a woman who witnessed the assault and may have filmed it.
