Police allege that a full-scale brawl between a group of teenage girls and men aged 21, 23 and 29 in Sydney at 9:40pm.

According to footage posted online, the men were "having a go" at a group of young boys before the girls intervened.

One of the girls also claimed that one of the men pushed one of the girls first, which is when she started to record the incident.

At one stage, a man can be seen dragging a girl by her hair and throwing her over a ledge before punching her.

One of the girls posted about the incident on social media, saying she has "never witnessed a more disgusting act in my life".

“The most low life men you could ever come across,” she said.

The riot squad was called and quickly arrested the man a short time later, with NSW Police charging the men with affray and common assault.

The men were refused bail and are due back in court on Tuesday.
