Rollercoaster death appeal

Hayley Williams was studying for her GCSEs

Police investigating the death of a teenager at Wales' biggest theme park are renewing an appeal for pictures of the tragedy.

Hayley Williams, 16, from Pontypool, south Wales, died after falling 100ft from the Hydro water rollercoaster at Oakwood theme park near Tenby in Pembrokeshire.

The accident happened on 15 April during the Easter holidays and detectives say visitors who took pictures or video may be able to help their investigation into the accident.

An appeal for anyone with images to come forward was made immediately afterwards, and that has now been renewed.

An inquest into Hayley's death has been opened and adjourned by the Pembrokeshire coroner Michael Howells

The hearing at Milford Haven on Tuesday was told the schoolgirl had suffered injuries to her body which caused internal bleeding.

Police have been interviewing visitors to Oakwood

On Monday, the first day back at school after Easter, a service was held at St Alban's Roman Catholic School in Pontypool to help Hayley's classmates come to terms with their loss.

She was a talented musician and a recording of her singing a composition written for her GCSE in music was played at the service.

The teenager had been with her mother and sister on holiday at the family's caravan in Pembrokeshire.

She was airlifted to hospital after falling from the ride but later died.

A joint investigation into the accident is being carried out by Dyfed-Powys Police and the Health and Safety Executive.

Fifty police officers working on the investigatio have been contacting holidaymakers from across the UK who were at the park on 15 April.

The accident was the first major incident in the 17 year history of Oakwood park, which attracts hundreds of thousands of visitors each year, and its owner has spoken of his "devastation" over the tragedy.

According to the park's website, Hydro is closed until further notice.

Anyone who has video footage or photographs should contact police at Pembroke Dock on 01646 682121.
