This terrifying image shows a teenager teetering over a cliff edge in a reckless stunt.

He is balancing just by his left foot on a fence post a couple of feet from an 80ft drop, which is followed by a further 200ft plunge.

The youngster is carrying out the pose for a dramatic picture and one of his pals behind him is seen taking a photograph.

The group were photographed on Dover’s White Cliffs at Langdon, close to the Coastguard Station in early October.

It was a member of the staff there who took the image.

The Maritime and Coastguard Agency released the picture this morning and said in a Facebook post: “No dramatic photograph or selfie is worth risking your life for.”

"We want you to come home again after a day on the coast. If you see someone in danger on the coast, remember call 999 and ask for the Coastguard."
