Police were forced to move in after crowds of revellers descended on the Forest of Dean for an all-night rave.
Just after 3.30am on Sunday morning Gloucestershire Constabulary tweeted: “Police are currently in the Forest of Dean near to Speculation Car Park dispersing a rave.
“People are advised not to attend the area due to safety and Covid risks. This will likely take some time to resolve this issue.”
Gatherings of more than 30 people are still banned under lockdown rules.
Officers also blocked roads in the area after “intelligence which had been developed and identified that many of those attending were from outside the county”.
Some residents took to Facebook to criticise those attending the event.
One wrote: “I heard it at 4.30am, I hoped it had stopped very soon after because the police intervened… Makes me angry that some people think it is safe to do so, when it clearly isn’t!”
In a statement Gloucestershire Constabulary said: “Officers from Gloucestershire Constabulary have been working throughout the night to close down a rave in the Forest of Dean.
Police were called to the Speculation Car Park near Lydbrook and Parkend during the early hours of this morning (Sunday 2 August) and have been dispersing the group to ensure the event does not continue and that those attending leave as safely as possible.
“Sound equipment has been removed and officers closed a number of surrounding roads to prevent more people from attending.
“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.
“As part of the police response, two arrests were made for drug driving and two vehicles were seized.
“Officers want to thank the local community for their patience and reassure those living in the area that they understand how much of an impact an event like this can have.”
