A man was arrested and sound equipment seized by police when an illegal rave was held in Hockwold at the weekend.
Around 150 revellers were at the unlicensed event in Corkway Drove in the village when police arrived at about 8.15am.
Officers contained the area to prevent other people from entering, and arrested a 45-year-old man.
He was taken to the Police Investigation Centre in Lynn and later released on police bail pending further enquiries until Monday, February 10.
All sound equipment and speakers were seized during the event.
Sgt Andrew Crown said: “This action reinforces the message that Norfolk police take a zero tolerance attitude to this type of activity and will take action against those responsible.”
