A 15-year-old boy who jumped into water has been left with wounds "down to the bone" after being impaled on railings. 

Selsey Coastguard Rescue Team was called to Pagham Harbour near Bognor on Tuesday evening to find the teenager  caught on the railings at the harbour entrance.

The boy had two deep puncture wounds and was treated at the scene by  paramedics before being carried to the ambulance on a stretcher and taken to hospital.

Other emergency services were called to the accident which happened shortly after 5.30pm. They included Littlehampton Coastguard Team, Selsey Inshore Lifeboat, South East Coast Ambulance Service and the coastguard rescue helicopter.

No other information about the boy's condition has been revealed.

A spokesman for Selsey Coastguard has since issued a warning about tombstoning.

He said: "Tombstoning is a high-risk activity where people jump or dive from height into water, often from piers, jetties, cliffs and bridges.

"Changing tides and water depth, submerged items and cold water shock can cause death or life-changing injuries.

"Submerged hazards like rocks and metal work may not be visible and water may be shallower than it seems. Also, once in the water it may be impossible to get out.

"Reduce the risks and do not jump. Instead, try coasteering with a registered provider. They will provide the necessary training and equipment to make the experience both safe and enjoyable.

"Never go into water while under the influence of alcohol, drugs or peer pressure."

People are being reminded that there are strong currents and underwater obstacles at Pagham Harbour entrance so they should not dive or swim in the area.

People should call for help when they are in an emergency situation at sea, on the beach or along the coast by calling 999 and asking for the coastguard.

Selsey Coastguard Rescue Team said this was its 112th call-out of the year so far..
