SHOCKING footage shows the moment a Halloween brawl broke out in a city centre.

Stunned bystanders watched on as the chaos unfolded in Picadilly Gardens, Manchester, last night.

A YouTuber known as Cozzy was seen confronting two people who appeared to be dressed as Playboy bunnies.

In the video, Cozzy is seen being flung to the ground.

Bystanders quickly joined the chaos, with punches flying as the brawl spiralled out of control.

Cozzy can then be seen hitting one of the men again.

As the pair begin to walk away, a man wielding a crutch is seen striking them on the back of the head.

It's believed the confrontation began after the pair appeared to take issue with being filmed.

In footage posted to his YouTube channel, the two are seen in a heated exchange with a group of young men before the YouTuber moves in closer with his camera.

Once they notice they are being filmed, they demand he stops recording before grabbing the camera, sparking the full-blown brawl.

Police have now launched an investigation into the "sickening" scenes in Piccadilly Gardens.

A Greater Manchester Police spokeswoman added: "We are aware of video footage circulating, which is currently being reviewed."

The Sun has approached Greater Manchester Police for comment.
