Workers at a sewage plant claim they are being haunted by visitors from the spirit world.
Hushed voices whispering in empty corridors, shadowy figures and orbs or balls of electromagnetic energy have all been spotted at the Eastbourne waste water treatment works in Prince William Parade.
Staff were so concerned by the strange visitations they called in a spirit expert and parapsychologist.
Treatment worker Mark Wey, who has worked at the centre for seven years, said: "People feel uneasy when they enter the building and the hairs on the back of your neck go up.
"A lot of people do not like going in there."
Mr Wey, who has had an interest in the paranormal for several years, claims to have seen a ghostly figure walk into the room out of the corner of his eye.
On another occasion he saw the heavy and unwieldy doors to the control room swing open on their own.
Another worker complained of the sensation of being watched when working in a chemical room. When he looked up, he said he saw the shadow of a figure.
Desperate for answers Mr Wey approached parapsychologist and medium Mike Kingscote to investigate.
After one night at the relatively new building at Langney Point the pair claim to have photographic and audio evidence to prove the ghostly visitations.
Mr Kingscote said: "I'm prepared to say there's a higher than average amount of paranormal activity at the site.
"We have pictorial evidence that you can't dispute.
"You can clearly see facial features and shadowy figures."
Most of the site was built during the Eighties with the oldest parts dating back to 1969.
The clairvoyant said the plant has higher than average levels of electromagnetic energy because of the water and energy passing through it.
He believes this acts as a magnet for paranormal activity from the surrounding area rather than from the site itself.
He said: "Most of the places I've been to that you would associate with hauntings like castles I've got little response from.
"It's the council houses and modern living places where there's most activity.
"I gather someone was murdered on the beach in the Twenties and someone actually drowned on site in the old part of the building.
"I think this last person was a very active energy there and is very protective of people who work at the plant.
"None of the presences are bad there."
A Southern Water spokesperson said: "Mark has a personal interest in the afterlife and found our underground site at Eastbourne somewhat spooky.
"He organised this psychic investigation as part of his ghostly hobby and we hope the findings weren't too frightening."
