Thames Valley Police today repeated a warning that they will not tolerate illegal raves this summer.

The warning comes as police carried out another successful operation over the weekend to shut down an illegal rave.

Police were called to an illegal event set up in Whaddon, Milton Keynes, at about 12.35am on Sunday, which involved about 1000 people, and more than 400 vehicles.

It was the second illegal rave that police have closed down in recent weeks. On Sunday, June 15, officers closed down an event near Wantage.

Insp Pete Downing, of HQ Operations, said: "These two incidents demonstrate that we do not tolerate illegal raves. We will be closely monitoring this kind of activity over the coming summer months. We investigate and assess all illegal raves in accordance with the Criminal Justice and Public Order Act.

"We are concerned about the people attending events like these; as they often involve excessive amounts of alcohol or drugs consumed by large numbers without safety precautions in place. I would encourage the community to report any unlicensed events early to allow us to disrupt these illegal events before they begin.

"Our intention is to minimise disruption to the local community by stopping loud noise from revellers and preventing large amounts of traffic coming into small villages during the night. This in turn will prevent damage to local landowners' property and allow members of the public who wish to use the land for dog walking and other lawful recreational purposes to do so."
