The four family members killed in a devastating mid Wales reservoir car plunge tragedy have been named by police.

Emyr Glyn Griffith, 66, Phyllis Iris Hooper, 84, Peter Briscome, 14, and Liam Govier, 14, all died in the tragic car smash, said Dyfed Powys Police.

Denise Griffith, 55, was at the wheel of the Peugeot 807 but survived to see her husband, mother, and two teenage foster sons killed.

The accident happened at Bwlch y Gle Dam, Llyn Clywedog, Llanidloes, on the B4518, during the family's early Easter break. The family members, from Pontypridd had been holidaying together in the Machynlleth area.

A Peugeot 807 carrying the five people careered off a road after apparently being "clipped" by another car.

23-year-old man, arrested on suspicion of causing death by dangerous driving, has since been released on police bail. The man, from the Llanidloes area, was driving a Ford Mondeo which has been seized by police for examination.

Neighbours of the family reacted with shock as the names of all four victims of the crash were released.

John Davies, a neighbour in Barry Road, Pontypridd, where the family lived, said he could hardly take in the news. "This is so tragic," he said. "They were such a nice family. People who would do anything for you. Denise was a foster mother and a lovely woman.

"Her brother Lloyd (Hooper) lives in the same street and was on holiday himself with his wife and three children when this happened.

"He had rented a caravan for a week in Kidwelly and had to leave it to go up to mid Wales yesterday. I spoke with him briefly in case he had not already heard, but he had. He was understandably very upset. Obviously he had just lost his mother, brother-in-law and the two boys."
