Police swarmed Melbourne’s Flinders Street Station on Saturday night after a brawl involving up to 10 people, some armed with machetes.

Witnesses have told police a group began fighting in the concourse area about 10pm.

A 17-year-old boy was found with lacerations to his arm.

He was taken to hospital for treatment.

Protective services officers (PSOs) apprehended four people who had boarded a train at the station.

They were allegedly found still armed with machetes.

Another two people were arrested nearby.

Of the six, a 22-year-old has been charged with affray, recklessly causing injury, assault with a weapon and possessing a prohibited weapon.

He has been released on bail to appear at the Melbourne Magistrates’ Court in November.

The remaining five, who ranged in age from 13 to 16, were released without charge while police continued to investigate the fight.

Police are appealing for anyone who witnessed the fight or has any information to call Crime Stoppers on 1800 333 000 or www.crimestoppers.com.au.

The fight in Melbourne occurred just days after it’s alleged a group of youths stabbed a homeless man in the regional Victorian city of Bendigo.

A 16-year-old was arrested by protective service officers at the Bendigo Railway Station last night.

Victorian government frontbencher Harriet Shing insisted the state’s machete laws, which came into effect last year, were working.

“Since Australia’s first machete ban was introduced in Victoria, we’ve seen around 18,000 weapons surrendered or seized, and we’ve also taken 17,000 machetes off the shelves,” Ms Shing said.

“We also know that it is our police and our PSOs that are doing the hard yards on the ground to make sure that incidents like these can be investigated, that we can reduce the harm that these weapons cause and that we can make sure that people are made and kept safe.”
