A 12-year-old Halifax boy is recovering in hospital after he fell from a rollercoaster.
Witnesses saw him hanging from the Excalibur 2 ride at Camelot theme park, Charnock Richard in Chorley, Lancashire.
A spokesperson for Wrightington, Wigan and Leigh NHS Foundation Trust said his condition was comfortable and stable and improving slightly.
An onlooker said he saw the boy fall from the ride. “It was probably the most horrific event I have ever witnessed,” he said.
The ride, which has height restrictions in place, swings riders into the air. It is classed as a “real challenge” and is said to “shake even the most fearless of thrill seekers”.
It is thought to have opened ten years ago.
A joint investigation is now underway between the Health and Safety Executive and Lancashire police.
A spokesperson for Camelot Theme Park said: “We are in contact with the boy’s mother and our thoughts remain with her and her family at this difficult time.”
They have launched their own internal investigation and although the park remains open, the ride is closed.
“The safety of visitors to the park remains our number one priority. Every ride undergoes a daily, pre-opening safety and maintenance check throughout the season and is subject to an annual, independent safety inspection,” she added.
“Excalibur 2 will remain closed until our internal investigation is concluded and the HSE confirms that the ride can re-open.”
