FOUR men have been charged after a violent brawl involving up to 30 footy fans — many using roadworks equipment as weapons — erupted before last night’s A-League match between Sydney FC and Melbourne Victory in Surry Hills.

Horrified onlookers said a large group of 15 “roused-up” men started walking towards Central Station on Devonshire St before grabbing nearby roadworks poles, about 6pm.

They then clashed with another group of 15 males walking in the opposite direction.

Video footage shows the large group of men throwing the poles at one another.

“They started fighting at Ward Park, it all happened so quickly, there was lots of screaming and they seemed roused up before they got there,” witness Michael said.

He said police were on the scene quickly and he believed capsicum spray had been used.

Surry Hills police confirmed they received multiple triple-0 calls to Ward Park about a fight but the crowd ran away when they arrived.

It is believed the fans of both clubs clashed while on their way to Allianz stadium to watch the match, but the crowd dispersed before police arrived at the scene.

Four Melbourne teenagers were charged with affray and violent disorder.

Each of the four men were granted conditional bail and will appear in the Downing Centre Local Court in Sydney in April.

A 24-year-old man who was with the four men during the arrest was also found to be carrying a small amount of the drug ecstasy.
