Concerns over ‘a stupid and dangerous practice’ involving a South Pembrokeshire charity holiday home have been raised this week.

In a letter to the Observer this week, Miss A. M. Tones, of Castle Court, Castle Square, Tenby, said: “For people who may not know, Harriet’s House in Castle Square, Tenby, is a specially adapted cottage where families with severely handicapped children and adults can enjoy a holiday together.

“Imagine my horror then when last Friday evening I saw a group of young boys and girls, who had been swimming off the end of the harbour, come running into the square and proceed to climb onto the roof of Harriet’s House. Apparently, the idea is they go to the far end of the roof tops and jump into the sea.

“They were climbing on top of the wheelie bins and food waste bin and hauling themselves up. Some individuals even stood on the window ledges and climbed up the wall.”

Miss Tones was even more horrified.

She continued: “The house was occupied at the time by four adults and a severely disabled young lady in a wheelchair. Imagine how upsetting all this was for them. I wouldn’t blame them if they never wanted to come back to Tenby.

“Needless to say, they were told by the occupants of the house to get down and the one boy left on the roof climbed down the wall leaving a trail of dirty marks behind him. I am disgusted by their behaviour as they obviously have no respect for anything, even their own lives.”

Miss Tones added: “I write this letter in the hope that the individuals concerned and their parents read it and see sense. It’s a stupid and dangerous practice and if they were to slip and fall may quite easily find themselves in a wheelchair and staying in Harriet’s House.”

The incident has led to the charity appealing for witnesses to contact the local police.

When contacted by the Observer, Elizabeth Sleight, on behalf of the Harriet Davis Trust, said: “The Harriet Davis Trust shares Miss Tones’s concerns. Apart from the obvious trespass and damage caused to our own and adjoining properties, this highly dangerous behaviour will inevitably lead to a tragic accident.

“If anyone has any information about the young people involved in this, they should contact the Neighbourhood Policing Team on 101.”

Tenby harbourmaster Matt Broadhurst warned that it was a ‘tragedy waiting to happen’.

“We’re not trying to be killjoys, but’ it’s dangerous.

“The culprits are on private buildings and trespassing, so they need to show some respect for other people’s properties.

“Yes we’ve all jumped off the pier in the past, but just because it’s always been done, doesn’t make it right,” added Matt, who said that there would be a ‘Breakwater’ event taking place at Tenby harbour this month, inconjunction with the local emergency services to raise awareness of the dangers of such matters.
