Residents in Brisbane’s north have told of a riot on their streets with up to 300 angry concert goers attacking police and each other.

The group was kicked out of a nearby hip-hop music festival at the Triffid in Newstead last night, after an aggressive punter begun kicking doors and windows inside the venue.

Their actions forced organizers to shut down the concert up to three hours earlier than scheduled.

But it only angered those in line outside, waiting to get in.

They began chanting "f--- the police" before one group kicked and jumped on an unmarked patrol car.

The officers inside the vehicle were forced to reverse and retreat.

The angry mob then turned on each other, punching and kicking until several were on the ground.

"This was just a small group that triggered such a bad mob mentality,” witness Shaun said.

He was at the Triffid bar with his girlfriend when the chaos broke out, and told 9NEWS the violence erupted inside, before it spilling out onto the streets.

"Police responded really quickly they definitely took control of the situation,” he said.

Nobody was seriously injured, but despite dozens of arrests, no charges were laid.

Police issued seven fines, all for public nuisance.

The owners of the Triffid today told 9NEWS in a statement it was "devastated" by last night’s events.

"The thing that upsets us most about this situation is that a night that was supposed to be about having an amazing experience and celebrating live music was overshadowed by the stupidity of a small group and put our staff and patrons at risk.
