The 30-year-old man was left lying unconscious on the road where a group of friends protected him until paramedics arrived. Sergeant Johnston described the brawl as ‘‘brutal’’ and ‘‘vicious’’ and said it was lucky no one was killed in the fight. Police described the brawl as ‘‘brutal’’ and ‘‘vicious’’.

The victim then stands up and staggers onto the footpath where he attempts to intervene as the men continue brawl. Footage shows the man then being pushed again by two men and he falls backwards and hits his head on the ground. Another man is kicked in the face as the fight spilled on to the middle of Chapel Street in front of traffic. As the brawl continues at least four men set upon the same injured man throwing punches and kicking him until he is cowering on the ground. Police have an uphill battle on their hands to identify those involved and the motive behind the fight.

At this stage it is unclear why the fight began or how many groups were involved. ‘‘Victims are co-operating at this point but unfortunately they don’t remember much as two were knocked unconscious and one has minor memories in the lead up to the brawl occurring,’’ Sergeant Johnston said. The fight escalated as the group of young men moved into the middle of the road. Credit:Victoria Police Police are analysing CCTV that shows some of the men turn up Greville Street after the fight. Investigators have called anyone who witnessed the assault to come forward and assist police to catch the other men.
