Around 1,000 people were removed from a rave in a village barn in Weston Underwood on Sunday morning.
Police were called around 1am and police made sure the music was switched off, and people were moved away 3am.
Superintendent 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 affected by this unlawful activity.”
