Police shut down an illegal rave in Norfolk after receiving a tip-off that it was being advertised on social media.

Officers were called at 7.30pm on Saturday by a member of the public who spotted the event on Facebook.

They launched an investigation and discovered around 600 people enjoying a party at Massingham Heath near Grimston, King’s Lynn.

After monitoring the rave overnight, specially trained support officers were sent in to disrupt the event at 3.45pm on Sunday.

Three men, aged 25, 28, and 31, were arrested in connection with organising the party.

Two others, aged 20 and 33, were arrested at the scene on suspicion of drug driving.

Officers also seized sound equipment, including a rack of speakers which were photographed wrapped with police tape.

Norfolk Constabulary’s Temporary Assistant Chief Constable Nick Davison said: “A significant policing operation was held today to ensure the event was disrupted and closed down safely, while securing evidence with a view to prosecuting organisers.

“The action taken today falls in line with our robust approach to tackling such events.

“Raves, not uncommon at this time of year, can be very disruptive for local residents and landowners while the presence of hundreds of people and vehicles can also have a detrimental impact on the environment.
