Thousands of pounds worth of music equipment was seized at an unlicensed music event in Oulton near Lowestoft.
Police were called at 6.30am on Sunday, March 1 after a member of public reported loud music on marshland near Queens Highway.
Around 200 people and 45 cars had gathered on the land and police seized six large speakers, two turntables, a generator and a nitrous oxide cylinder.
Inspector Anthony Bridgland said: 'Suffolk Police will not tolerate unlicensed music events (UMEs). We are investigating this UME and have seized thousands of pounds worth of equipment.
'I would like to remind people that UMEs are illegal, uncontrolled and unsafe. You risk prosecution and you put yourself in danger by attending.
'These uncontrolled events have no medical facilities to help you if you become ill or suffer an injury. To help us prevent and disrupt UMEs I would ask our local communities to be vigilant and report any suspicious activity. This could be a gathering of people, loud music or increased vehicle activity in a rural or remote location.'
Anyone with information should call Suffolk Police on 101, or Crimestoppers anonymously on 0800 555 111.
