A large rave was broken up in a barn in a village on the Northamptonshire border on Sunday afternoon.
Thames Valley Police, supported by Northamptonshire Police, stopped the large rave in Weston Underwood, near Olney.
Police were called to the event shortly before 1pm, following reports that around 1,000 people had gathered in large barn in the village.
Superintendant Barry Halliday, the Milton Keynes Local Police Area Commander, said: “As soon as we became aware of the rave together with our colleagues from Northamptonshire Police we responded promptly with a significant number of officers to ensure those numbers did not increase and we utilised our powers available to us to minimise disruption.
“Police do not consider this type of activity to be acceptable. It has caused a lot of concern among local residents as well as considerable traffic and parking issues.
“We fully understand the impact these types of events cause to our communities and will review the event and seek to investigate fully any offences disclosed.
“I am very grateful for the assistance provided by Northamptonshire Police and also the local community who have been effected by this unlawful activity.”
It is understood that a large number of people attended the rave after police had dispersed a second rave near Irchester Country Park just hours earlier.
