A cheeky raver mooned riot police as they shut down an illegal rave at a popular beauty spot.
The reveller dropped his trousers and slapped his bare backside at shield-carrying, helmet-wearing officers.
Footage shows the man taunting police as the event – which attracted around 2,000 people – came to an end.

The clip also captures clashes between officers and ravers near East Lulworth, Dorset.
Police seized sound equipment and shut nearby roads as they moved in to break up the gathering, as reported by Need To Know.
Dorset Police confirmed 11 people were arrested.
The rave was first reported at around 11:45pm on Saturday, with officers working through until Sunday evening to bring it to a close.
East Lulworth lies close to Lulworth Cove, famous for its limestone arch landmark, Durdle Door.
Assistant Chief Constable Steve Lyne said: “While responding to the incident, our officers came under attack from missiles and faced a violent and hostile reception.
“Violence in our communities and against our officers will not be tolerated.
“These types of events are illegal and cause a significant disruption to communities – we must respond to ensure the safety of everyone and it is unacceptable that we are faced with violence while doing so.”
Under the Criminal Justice and Public Order Act, police have powers to stop vehicles within five miles of a rave and turn them away.
The law also targets gatherings of more than 20 people listening to music at night.
Viewers of the mooning clip were less than impressed.
One person said: “How embarrassing for his family.”

Another user added: “What a bunch of scruffs.”
A third viewer wrote: “Back to the nineties.”

And another person said: “So a group of people enjoy music in nature requires riot police but hordes of ‘teenagers’ running wild through city centres only gets PCSOs and CCTV monitoring, what kind of clown world are we living in?”
