Police have issued this shocking CCTV of a mass brawl outside a Manchester nightclub.
The video captures violence erupting outside The Black Dog Ballroom in the Northern Quarter some time after 1.20am on Saturday, July 1.
The fighting started, according to police, when half of a group of men were refused entry to the venue, the Manchester Evening News reports.
The clip shows scuffling and punches being exchanged before one man in a t-shirt aims a right hook at one of the others, sending him crashing to the ground.
It prompts a brief stand-off before other men then throw punches as the man who had been felled slowly gets back to his feet.
