Warnings have been issued by Herts police to illegal ravers following two disused warehouse events in St Albans.

On July 15 and 22, unused buildings in St Albans were taken over by young people attending unlicensed music events - there was music, drinking, drug taking, and dancing.

Seven hundred people attended the first rave in Campfield Road, which was busted by police following a tip off. The second time, on Camp Road, police received numerous phone calls.

St Albans Ch Insp Shane O’Neill has warned organisers his team will do everything to “pre-emt”, “prevent”, or “disrupt” any more events that might be planned: “Hundreds of people have turned up for the raves at disused warehouses, which is illegal and can be dangerous.

“Often the raves do not have an adequate health and safety procedures in place and young people are drinking and taking drugs.”

He also stressed the problems it causes for local communities, which include noise and traffic disturbance.

“Let me be clear, we will do everything in our power to put a stop to any unplanned raves and prosecute organisers and attendees who are breaking the law through anti-social behaviour, criminal damage or possession of drugs.”

No-one was arrested following the second rave.
