Gloucestershire officers were called overnight to the area at Speculation Car Park near Lydbrook and Parkend in southwest England, the Gloucestershire Constabulary said in a statement.
Police advised citizens to stay away from the beauty spot due to concerns over safety and COVID-19 risks. Gatherings of more than 30 people are currently banned in England to curb the spread of the virus.
Officers removed sound equipment and closed several roads to prevent more partygoers from arriving, the agency said.
“The road closures were as a result of intelligence which had been developed and identified that many of those attending were from outside the county which allowed officers to target key roads that the individuals would have used to attend,” the statement said.
Two people were arrested and two vehicles were seized, police said. Police did not immediately say how many people were in attendance.
Around 7 a.m. local time, a police spokesman said the operation had been “relatively successful” and was “coming to a close,” according to Sky News.
Large-scale parties have popped up across the U.K. since June, when two “quarantine raves” in Manchester attracted 6,000 people. An 18-year-old woman was raped, a 20-year-old man died of a drug overdose, and three others were stabbed during the events, police have said.
Another illegal rave last month in the city of Bath attracted 3,000 people and proved impossible for police to break up. Residents as far away as Bristol, some 8 miles away from the party, said they could hear the thumping music.
