Cops came under attack as they broke up a party that attracted 150 ravers last night.

The illegal music event was being held at a disused warehouse in the Digbeth area of Birmingham on November 28.

Bottles were thrown as cops tried to close down the event and restore order.

Everyone present had their details taken by officers and will be subject to a £200 fixed penalty notice, Birmingham Live reports.

The force tweeted details of the incident on Sunday morning, saying: "An illegal rave in a disused warehouse in Digbeth was discovered tonight.

"Around 150 people were inside, some started to throw bottles at officers. The building was contained by Response WMP, Operational Support Unit, FSU_WMP and many others.

"All persons were lead out in small numbers. Their details were taken and fixed penalty notices were issued for breaching lockdown restrictions. The fine is £200 to be paid within 28 days."

Under coronavirus restrictions, social gatherings between different households indoors are banned. This will also apply when lockdown is lifted on December 2 and Birmingham enters Tier 3.

Operation Reliant was set up specifically to track down breaches of Covid restrictions.

Chief Insp Stuart Bill, head of the West Midland Police's Operational Support Unit, praised the officers' work on Twitter.

He said: "Really challenging policing COVID regulations and balancing individual ECHR [European Court of Human Rights] freedoms with public health. We all have a part to play to help us recover quicker. Well done to all the officers involved with this."

The incident mirrors one in Yate, Gloucestershire, on Halloween, where 700 revellers raved on for 24 hours. Cops who moved in with dogs to break that illegal event up they were pelted with missiles, leaving some officers with minor injuries.

Avon and Somerset Police issued pictures of 38 people they want to identify after the rave at a disused warehouse in Beeches Industrial Estate.
