A lifeboat crew has issued a warning about the dangers of "tombstoning" after a teenager was seriously injured jumping into a harbour.

Dunbar RNLI said the 14-year-old injured his leg after plunging into the water at about 18:30 on Thursday.

Tombstoning is the practice of jumping straight and stiff like a tombstone from a high structure.

An inshore D class lifeboat was launched and found that the boy had managed to get himself out of the water onto steps near the harbour entrance. The crew took him to a waiting ambulance.

Dunbar RNLI lifeboat helm Laura Kirkham said: "Tombstoning, or cliff jumping, into the harbour might seem like fun.

"But there's always a danger of hidden rocks and unknown depths that can result in serious life-changing injuries and even death."

She added: "As tempting as it is to cool off in hot weather, we're urging people to think before they jump.

"The few seconds of thrill that come from tombstoning can lead to consequences that last a lifetime, not only for the individual involved but also for their family, friends and those who witness or respond to the incident."
