A fight at Stereosonic in Sydney was quickly quelled with the intervention of security.
Amateur video captured around 20 men brawling. One man, who was a party to the fight, was knocked out while the fracas continued. The vision shows security quickly on the scene and the fight subsequently dissipating.
