Superintendent Tim Metcalfe, said: “Illegal unlicensed music events are dangerous and there can be little regard for public safety.
“It is very early in the season, but the response to this event shows that we will continue to deal with reports of such events robustly.
“If someone becomes aware of an unlicensed music event taking place or information about a planned rave, this should be reported either online or on 101.
“If it is an emergency, please call 999. It is an emergency when a crime is being committed, there is a risk of injury, or there is a risk of serious damage to property.
“I would like to thank members of the public who called to inform us of this event and would also like to thank the local community for their support and patience”
