Police arrested seven people and seized two vehicles in relation to a rave on farmland near Bourne.
The rave started on land off Fen Road, Dunsby, at around 11pm on Saturday night.
At its peak between 200 and 300 people were thought to be in attendance, causing a significant amount of noise disruption to people living in the area.
Lincolnshire Police said there were insufficient officers on duty to disrupt the gathering safely while it was at its peak. Instead they contained and monitored the event.
At around 2.30pm on Sunday officers entered the site and closed the rave down. Seven people were arrested, two cars and sound systems were seized. Suspects are currently helping police with their enquiries.
