Young people in the Welsh seaside town of Tenby are causing chaos for a local charity by taking part in the “tombstoning” trend.

Footage of groups leaping into the sea have gone viral on social media captioned: “Got to keep the Tenby tradition going!”

The groups are climbing up the property of Harriet Davis Seaside Holiday Trust to get onto the roof and plunge into the water below.

Despite attempts to stop trespassers including anti-climb paint, removing adjacent bins and anti-climb spikes the charity says situation has got even worse.

There’s allegedly even been “deliberate damage to the fabric of the building.”

Their Senior Administrator, Carol Lincoln says there’s been a “serious failure” from cops to stop the “tombstoning”.

She warned there is an “extremely serious danger to life”.

Not only are the jumpers putting themselves at risk of serious injury and fatality, but Ms Lincoln said the youths are “terrifying vulnerable families staying in the property”.

She said: “We are now also experiencing youths hammering on our doors and windows as they climb onto and descend from the roof

“The young people are deliberately smearing the anti-climb paint over our external walls and are progressively ripping the plastic spikes from the roof.”

She added: “Our visitors are not tourists coming to the town for entertainment.

“Most of our visiting families come from , and some are local families.

“They are parents and carers looking after children and young people who may have profound disabilities, complex medical needs or life-limiting conditions.

“Many families are only able to have a holiday because our properties provide the specialist equipment and facilities they require.”

Ms Lincoln has demanded action from , parents and council officials to prevent serious injury and fatality.

County Councillor Michael Williams has written to police to back the charity, saying: “There is a genuine fear that there could be a fatality if this activity is allowed to continue.

“In my at the very least criminal damage is being caused by these youths and they are trespassing with intent, and I would ask that you consider taking action on these specific activities

“This amazing charitable organisation provides a unique opportunity for families who often have to contend with some of the most distressing circumstances conceivable and they deserve the support of everyone concerned.
