Police swooped on an illegal rave on Hounslow Heath, where more than 100 people had gathered.

Officers were called to the middle of the nature reserve last Friday (July 11) at about 9.55pm.

A police spokeswoman said they were able to stop the party before it had even got going, and the crowd was dispersed peacefully without any arrests being made.

In April, an illegally all-night party under the M4 flyover which crosses Boston Manor Park, in Brentford, led to complaints from neighbours.

In January, 16-year-old Tom Spargo-Mabbs died after a rave in a disused industrial unit in Hayes, and Hillingdon Council has since moved to crack down on similar impromptu warehouse parties.
