An illegal rave was shut down by police who found 80 people partying on farmland late at night.
The rave, held on farmland in Buckland, was closed following calls to police just after 1am on Sunday () and police are investigating who the organisers were.
Officers moved the crowd on and then removed equipment being used.
Police describe illegal raves as unlicensed events which have the potential to cause damage to crops, livestock and areas of outstanding natural beauty.
Organisers do not operate within the Licensing Act 2003 and so do not ensure the safety and wellbeing of those attending.
There is also concern about illegal drug use and the inhalation of legal highs such as nitrous oxide, known as laughing gas, at such events.
Insp James Davies, from Buckinghamshire Neighbourhood Policing Team, said: “Specially trained officers from Oxfordshire, Berkshire and Buckinghamshire attended a report of an illegal rave near to Buckland on Sunday morning, following calls from the public.
“With the support of the National Police Air Service we quickly identified the location of the rave attended by around 80 people on farmland.
“Enquiries and evidence gathering took place at the scene.
“People there were given a direction to leave before we used police powers to remove equipment. They complied with this request.
“Enquiries are now ongoing by Wendover Neighbourhood Policing Team to identify the organisers and take action.”
