Fears have been voiced that a child could be killed as youngsters continue to treat crumbling cliffs along the north Norfolk coast as a playground.

New footage has emerged of a boy dangling his legs over the edge of the crumbling cliffs near the golf club at Sheringham on Sunday - and then sliding all the way down to the bottom.

The high drama comes just weeks after the Coastguard reiterated its pleas to the public not to climb on the cliffs following the death of a man who was crushed underneath a collapsed cliff in Thorpeness, Suffolk.

A runner, who captured the latest drama on camera, said: 'I could not believe what I witnessed.

'I was running between Weybourne and Sheringham when I heard a faint shout coming from over the side of the cliff and when I looked back I saw one young boy perched on the top, dangling his feet over the edge.

'There was a group of four or five of them, with one already halfway down and looking like he was in a bit of trouble.

'I shouted to make sure they were okay and reminded them how dangerous it was and they replied: 'We know'.'

The north Norfolk coast has suffered a series of cliff falls in recent weeks after being battered by stormy weather.

The eyewitness added: 'All it would have taken was for another piece of cliff to go or for one of the boys to slip and we could have had another tragedy.'

Last month the Coastguard issued a warning to the public to keep clear of the cliffs after an adult and child were pictured climbing at West Runton close to where it had collapsed.

And last summer the emergency response team was left dumbfounded by the actions of a couple spotted appearing to pose for a selfie on the edge of a section of collapsed cliff at the Runton Road car park in Cromer.

A previous public announcement on Cromer and Sheringham Coastguard's Facebook page read: 'We strongly advise all members of the public to not walk under the cliffs or near to the edge on top and keep all pets away from the base at present. Shockingly children are still climbing the faces and digging significant holes into the cliffs.

'If your child goes to the beach please ensure that they are not doing this for their own safety. They could give way without any notice and collapse in or on top of someone.'
