BEACHERGOERS formed a human chain to drag a struggling swimmer to safety in a dramatic rescue at Durdle Door.

Witness Emily Foote said: "It was a very traumatic rescue by some very brave members of the public of a swimmer who owes his life to them all.

"It should serve as a warning of the dangers of the sea and tide especially in these winds as so many putting themselves at risk."

A spokesman for Lulworth Coastguard said "A large group formed a human chain in an attempt to rescue the individual at Durdle Door.

"Apparently, two were in difficulty at one point, the first casualty and the rescuer.

"We were pleased to hear that they were both recovered and were able to walk away.

"With the large waves and spring tides of late, we strongly discourage sea swimming and playing around in the surf, especially on exposed beaches such as Durdle Door.

"The undertow is very powerful and will have no trouble taking you off your feet. If you see any one in difficulty on the coast, call 999 and ask for the Coastgaurd."
