More than 35 people held an illegal rave in fields behind a residential road.
Officers shut down the rave off Halewick Lane, Sompting, earlier this morning (June 8) They were called by a dog walker to say 35 people with vehicles and large music speakers were on land next to the nearby recycling centre.
As officers moved in, more people were arriving in taxis.
The party goers packed up and left the site around 9am.
Chief Superintendent Tony Blaker said: "The earlier that police are alerted to a rave taking place, the greater the chance of preventing them becoming established, disrupting them and dispersing those responsible for their organisation.
"In this case we were able to respond swiftly and the revellers left without causing any disruption."
The gathering follows a larger rave held at Devil's Dyke two weeks ago. It was estimated 2,000 people attended th event.
