Recent incidents have resulted in injuries
The Island's police are warning of the dangers of tombstoning.
The Police Early Action Team says there have been incidents in recent days where youngsters have jumped from piers into harbours, resulting in injuries.
There is a particular concern over those jumping into Douglas, Ramsey and Peel harbours, as there could be a danger posed by ferries and fishing vessels.
Officers warn this is illegal and can result in serious injuries, including paralysis.
