Shock video has emerged online showing a huge brawl at the doorway of a nightclub that ends with a man firing a gun during the melee.

The footage initially shows a man falling through the door past a group of bouncers. He is pursued by a burly gang of men who the door staff then start trading punches with.

One of the club invaders is knocked out in the barney but just as it looks as if the bouncers have got the upper hand a muzzle blast from a gunshot can be seen as an armed man enters the premises with others in tow.

The imposing gunman then fires another round from his firearm as he strolls into the club hallway and forces the bouncers too retreat. He then gathers his friends as they prepare to exit the bar.
