Lee Roberts and Paul Stevenson were doing a practice live broadcast from the notorious poltergeist hotspot ahead of their scheduled Halloween visit. However while filming themselves creep around the infamous 30 East Drive in Pontefract, West Yorkshire, they claim a doll in one of the bedrooms was used by a poltergeist or demonic force to scare them. The terrifying footage shows porcelain doll 'Victoria' in her box with the lid on when they first go in the bedroom.

However when the return moments later the doll has moved and the lid is completely off and has been bent out of shape, leaving the pair then checking the house for an intruder in panic.

There's definitely a dark presence - it could be a demonic presence Lee Roberts, ghost hunter

The house was the site of one of Britain's most notorious alleged hauntings when the Pritchard family were subjected to years of torment by the so-called 'Black Monk of Pontefract'. Mr Roberts, 39, believes the Black Monk is a 'dark spirit', possibly 'demonic', who used Victoria to scare the ghost hunting duo into not returning on Halloween. Mr Roberts, from Sutton in Ashfield, Nottinghamshire, said: "It was very unexpected. You can go and try and get something on camera and never get anything.

"We were only testing the signal really but things just started to happen so we kept rolling. "We're going back on the 50th anniversary of when things first started happening to the Pritchard family in that house. So even if nothing happens it's still nice to mark this. "We started hearing a few knocks and bangs quite quickly but I usually put those down to it being an old house, from a scientific point of view. "But we had not heard anything like this before and next door was away so there was no noise coming from there.

"The doll Victoria was apparently found in the attic of the house but no one knows where she came from or who she belonged to. "The box actually has a warning on it saying that if you wish to look at Victoria you should not take her out of the box and always cover her back up. "I'm sure it's there for effect but it's quite unsettling to read that in the dark as your mind starts playing tricks on you." The footage, caught on September 20, shows the duo come into the bedroom and film the position that Victoria is lay in, with the lid to the box covering her face.

After leaving the room, Mr Roberts claims that they both saw the shape of a figure move across the hallway with 'wavy black hair', just like the doll, followed by a loud bang so had gone back to the room to investigate. Mr Roberts, who runs Haunted Events UK with Mr Stevenson, said: "When we returned to the doll and put the light back on her she had moved - just after we had heard some bangs in the house. "You can clearly see the reaction on camera. I was speechless. Paul was adamant someone was playing tricks on us and wouldn't even come into the room he was so scared." The footage shows Mr Stevenson then claim he heard someone call out 'Lee' so the duo panic and begin rushing downstairs in fear to check the doors are locked.

Mr Roberts said: "We didn't know what was real and what wasn't. If someone had been in there toying with us then that's even scarier than a ghost haunting us. "It was a really, really frightening 90 minutes. As we left the door swung open but it wouldn't do it again when we tried. It looked like a yank. "I definitely think it was some presence doing it. We were just about to leave so I think it was something there warning us to say 'don't come back'. "I should not be scared of going back at Halloween as that's my job, this is what I do. However on the flip side I am quite apprehensive about what could happen.

"Should we really be messing around with this? Obviously something doesn't want us there. The stuff that happened with the doll really makes me nervous. "Lots of people refer to him as the Black Monk but looking at the history of the location, I don't think he was a monk. "I believe there is a dark figure there and people associate that with a monk. But there's definitely a dark presence, but I don't know if he was ever living - it could be a demonic presence. "The doll is not actually the issue, it's what is controlling the doll and making it move, that's the scary part.

GETTY Lee Roberts believes the house is haunted by the ghost of the Black Monk

"Why is this thing in 30 East Drive? Why does it stay there? We need an open mind to find out what is in there and figure out if it is real or if something needs help to be let out." The duo's footage includes them running in fear down the same set of stairs where 14-year-old Diane Pritchard was allegedly dragged by the hair by the supposed Black Monk. Mr Stevenson, 47, said: "The house frustrates you, it annoys you at times, but there's something dark there and at times it scares the sh*t out of me. "The beauty of it is that it's not a castle, it's not a 14th Century coaching inn, it's a former council house, in the middle of an estate - unassuming but with a dark secret."
