Tenby RNLI lifeboat volunteers have taken part in a further multi-agency exercise, in light of concerns over ongoing ‘tombstoning’ incidents around the seaside town’s harbour.br Authorities stated over the summer that several injuries and ‘broken bones’ had been sustained during the school holidays, due to youngsters taking risks by jumping off heights around the seaside town’s harbour area into water below.br Such incidents forced Pembrokeshire County Council to issue more warnings over the dangers of jumping off the pier at Tenby harbour and other parts, following an increased impact on services.br HM Coastguard and the RNLI also highlighted once again the serious risk of injury that jumping from height into the sea can cause, especially near working boats - which is extremely dangerous and can have serious consequences.
