Charges of manslaughter could be brought after a teenage girl plunged 100ft to her death from a rollercoaster ride at a west Wales theme park.
Hayley was on holiday when the incident happened
Hayley Williams, 16, received fatal injuries in the fall from the Hydro ride at Oakwood Park in Pembrokeshire last month.
A report to members of Dyfed-Powys Police Authority says they have asked the Crown Prosecution Service to consider both manslaughter and health and safety offences.
Police have interviewed 96 people so far over Hayley's death.
The investigation into her death is still being carried out by the police and the Health and Safety Executive.
An extract from the report, to be presented to police authority members on Monday, said: "Liaison has taken place with the Crown Prosecution
Service in Birmingham (corporate specialists) and a full examination and process
has been requested with consideration for manslaughter and health and safety
Ambulances were called to the Hydro ride - described by Oakwood as "Europe's fastest and wettest water coaster" - after Hayley's fall on 15 April.
Ten-year-old Martin Rothwell was treated for head injuries after he was struck on the head as Hayley passed him.
Hayley was flown by air ambulance to Withybush Hospital in Haverfordwest, but within hours Dyfed-Powys Police confirmed that she had died.
The teenager - a pupil at St Alban's RC High School - had been with her mother Beverley and younger sister Hannah, 13, on holiday at the family's caravan in Pembrokeshire when the incident happened.
A spokeswoman for the park said they were "not aware of any development" in relation to possible charges.
