Ghosts hunters say they have caught their clearest-ever evidence of spooky activity on camera during a recent trip to a haunted site.
Linzi and Lee Steer, who run Project reveal - Ghosts of Britain say their latest capture is the clearest image they have taken in their decades of ghost hunting experience.
The couple from Rotherham, who have over 20 years of paranormal research experience between them, have snapped what many of their fans believe is an apparition in the form of a ghostly face.
The experienced investigators live stream all their hunts and they were alerted to the spooky visage when fans spotted it on a Facebook clip, Yorkshire Live reports.
"I just can't get over it. It is so clear and distinctive," said Linzi.
The pair spotted the photo after a visit to Inveraray Jail.
The couple, who go on daily ghost hunts, live-stream all of their investigations on Facebook and ask viewers to screenshot any unusual sightings.
But when they looked back at the photos from their trip to the Scottish jail and courtroom, they were left shocked.
A figure can be seen behind a waxwork model in multiple screenshots, according to Linzi.
While she said she could not see the figure while she was filming, she has been left unable to explain what her viewers saw.
Linzi said: "We try to debunk everything, but there's no dummy there in that particular area."
She added: "It is definitely not human. If it was one of us you could tell with the colouring, but it looked very transparent."
The apparent figure wasn't the only spooky part of their trip either.
Husband Lee revealed he had an unnerving experience when looking around the site's jail blocks.
"I walked into one of them and I felt a tickling sensation on my throat, and it started to get more intense to the point where I had to run outside," he said.
Although they didn't know it at the time, the couple were later told by staff that many people have reported feeling a choking sensation in the same spot.
Lee added: "That is the first time I've ever felt that kind of thing. I'm actually sceptical when it comes to ghosts."
