Norfolk police declared a major incident early today after a mob of 100 bottle-throwing people attacked Yarmouth police station.

The drama unfolded after police arrested three people in a van with sound equipment thought to be destined for an illegal rave.

Police formed a line to protect the police station as beer and wine bottles were hurled at the building.

Two police vehicles were damaged and officers narrowly avoided serious injury from missiles.

Chief Superintendent Bob Scully said the arrested trio were not involved with the “inexcusable” attack at the station, but officers were linking the arrests with the incident.

Two police vehicles were damaged by the mob and officers narrowly escaped serious injuries.

Shortly after the mob dispersed, an illegal music event was reported in a warehouse on the town's Harfrey's industrial estate.

Chief Supt Scully said: “What occurred was entirely unacceptable - large scale anti-social behaviour carried out by a large group of people - and is inexcusable. This behaviour and activity simply won't be tolerated.”

Chief Supt Scully said people should stay away from the industrial estate, because it was a crime scene.

“We are taking this matter extremely seriously and are looking to bring this situation to a swift conclusion,” he said.

At about 10am police began action to disperse the revellers, initially thought to be 200-300.

Anyone with information about the town centre incident or the rave is asked to call police on 0845-4564567.
