Footage shows hundreds of people ignoring social distancing rules at an illegal forest rave in Norfolk before it was broken up by riot police at a cost of ￡25,000.
The mixture of drone, helicopter and bodycam video was shot on Saturday night as officers broke up the party at an isolated area of woodland in Thetford Forest off the A134 at Lynford, near Brandon.
Norfolk Constabulary, which said some officers were pelted with bottles and cans by ravers during the shut down, have since made the shocking footage public.
In one clip, a partygoer is seen performing a flying kick at officers before being batted away by a riot shield.
More than 100 officers from four police forces were needed in what has been described as a "significant operation" at a huge cost to the taxpayer - with more than 500 people in attendance.
The gathering was successfully quelled and audio equipment, generators, the rig and a large flat-bed lorry were seized.
Five people were arrested and handed fixed penalty notices of ￡100.
Assistant Chief Constable Nick Davison, who led the operation, said a drone unit, dogs, the National Police Air Service helicopter and specially trained public order officers had all been deployed.
The event was taking place near to the English Heritage site Grimes Graves.
Ch Cons Davison said it was clear the "well-established and planned event" was due to continue through Sunday and into Monday and the force had worked to "close the event down in a controlled manner, taking the safety of those in attendance and our officers into account".
He said: "It's extremely disappointing to see these types of events taking place when the rest of our communities are doing everything they can to help stop the spread of the virus."
It was just one of multiple raves shutdown across the country this bank holiday weekend.
In London, the Met Police said it had shut down 21 unlicensed music events.
New rules which came into force on Friday ahead of the bank holiday weekend mean organisers of illegal raves could be hit with ￡10,000 fines.
