A new ride at one of Britain's biggest theme parks has been moved after fears that it had disturbed an ancient burial ground, prompting paranormal activity.
Workers creating the water ride at Thorpe Park in Surrey, England, said they started noticing ghostly sightings nearby, including what appeared to be a headless monk.
There were reports of objects being moved, workers feeling like someone was watching over their shoulders and sudden cold feelings being experienced.
A paranormal detection agency was called in to carry out tests and found that an ancient burial ground or settlement could have been disturbed.
The 64ft-tall water ride, Storm Surge, was originally planned for an area known as Monk's Walk, an old footpath that has linked the ruins of nearby Chertsey Abbey to Thorpe Church since 666AD.
Mike Vallis, divisional director of Thorpe Park, said: "It became apparent that something strange was going on when teams started clearing Storm Surge's initial site.
"Staff reports of eerie goings-on shot up and the only physical change in the park, at that time, was the beginning of ground preparation work for the new ride.
"As employees were getting freaked out, we decided to call on an expert."
Jim Arnold, of South West London Paranormal, said: "We carry out these kinds of investigations quite regularly, with medium to weak results being reported on a weekly basis.
"Thorpe Park, however, was more striking as results were picked up immediately.
"The results were so strong, we felt the only explanation could be that an ancient burial ground or settlement was being disturbed, prompting the extra paranormal activity."
Forensic geophysicist Peter Masters has since been called in to analyse the site, using deep ground radar.
He said: "From the preliminary investigations, we have picked up signatures similar to that of a burial ground -- possibly ancient."
