CHILDREN were spotted climbing over a sealed off jetty and tombstoning in Canvey. 

On Monday, members of the public and workers on the seafront raised the alarm to after spotting the reckless kids were putting themselves in danger.

Witnesses saw how they were climbing over a sealed off jetty to obtain access for tombstoning.

Crews from Southend Coastguard, based in Shoebury, attended the scene and provided safety advice about the dangers of jumping from a height into water.

Bev Allen, HM Coastguard controller, said: “Jumping from piers, cliffs, rocks or other structures into the sea can be very dangerous - there's a reason we refer to it as tombstoning."

It comes after an incident last month, which saw a man be rescued after jumping from Southend Pier.

If you see anyone in trouble on or near the coast, don’t hesitate to call 999 and ask for the coastguard.
