A THEME park faces prosecution by the Health and Safety Executive (HSE) over the death of schoolgirl who plunged 100ft from a white knuckle ride.

Sunday school teacher Hayley Williams, 16, of Pontypool, was ejected from the top of the spectacular Hydro ride as it began an almost vertical descent into a plunge pool.

It happened at Oakwood Theme Park, Narberth, west Wales, in April 2004 as horrified visitors looked on.

A spokesman for the HSE said today: "We can confirm that a decision has been made regarding the involvement of Oakwood Leisure limited in the incident in 2004 in which Hayley Williams died.

"The HSE has met with Oakwood Leisure limited and informed them that it is the intention of the HSE to prosecute them under the Health and Safety at Work Act 1974.'' A spokeswoman for the theme park said: "We have been given notification by the HSE that they intend to prosecute Oakwood under Section 3 of the Health and Safety at Work Act 1974 following the death of Hayley Williams at the Park in 2004.

"We will continue to co-operate fully. However, since their investigation is still ongoing, we cannot comment further on this matter at this time.''
