Around 300 partygoers caused chaos when they descended on an East Cambridgeshire village ready for an illegal rave.
The festivities were set to get underway at a farm in Lode, about six miles to the north east of Cambridge city centre, in the early hours of Sunday morning (June 16).
But quick thinking residents alerted police - who were able to stop the rave from getting underway.
Officers arrived to find 80 vehicles had gathered at site.
