New video footage shows riot police being attacked as they broke up a huge rave over the Bank Holiday weekend which attracted around 500 revellers.
In the clip one man is seen kicking out at officers as more than 100 shut down the mass gathering on Sunday.
Officers were also attacked with bottles and cans as they disrupted the rave - which was first reported in Thetford Forest in Norfolk on Saturday night.
Five people were arrested and fined £100 for attending the unlicensed music event, Cambridgeshire Live reports.
Investigations are underway to identify the event organiser, who could face a £10,000 fine under a new law to deter mass gatherings due to coronavirus.
Police first attended at about 11.20pm on Saturday after a member of the public reported seeing large numbers of cars queuing to access a fire route.
A number of resources including the drone unit, National Police Air Service helicopter, dogs and specially trained public order officers worked to close down the event.
Officers seized audio equipment, generators, the rig and a large flat-bed lorry which was used to transport the equipment.
Assistant Chief Constable Nick Davison, of Norfolk Police, said: “We understand the disruption such events cause to local communities and the concern people will have, particularly as coronavirus continues to be a real threat.
“This was a well-established and planned event and we needed additional specialist resources to shut it down safely.
“I would like to thank local residents once again for their patience and understanding while we worked to close it down.”
