Man Fights For Life After Melbourne Street Brawl

The fight broke out as 200 people were leaving an event.

An 18-year-old man is fighting for life after a car slammed into him, crushing his leg, during a wild brawl on an inner Melbourne street following a record label launch.

Up to 200 people were involved in the melee that spilled out on to the road from the Gasometer Hotel on Smith Street in Collingwood in the earlier hours of Sunday.

"During the affray, a car has collided with a number of parked cars on Mater Street and pinned one person against the parked vehicle," police Commander Tim Hansen told reporters.

"He sustained a serious leg injury."

The man remains in a critical but stable condition in The Alfred hospital. Six other people were also injured in the brawl while three cars were damaged, and police are still searching for the instigators.

Victoria Police are narrowing in on the driver of the car that critically injured the man and expect to catch up with the offender by Monday. No arrests have been made as yet.

Three patrol cars were on duty to keep an eye on the 66 Records launch and police had flagged the venue for monitoring after recent crimes involving the Pacific Islander and African communities.

Commander Hansen said there had been no intelligence in the lead-up that it was going to be a high-risk event and the escalating behaviour came out of left field.

Event organiser J-Nelly told revellers to be on their best behaviour in a Facebook post on Friday, saying "violence will not be tolerated".

"A moment of anger isn't worth a lifetime of bad labeling (sic)," he wrote.

Anyone who witnessed the incident or who has information have been asked to contact police or Crime Stoppers on 1800 333 000.
