Siobhan McAuley headed the group as they visited what is considered one of the world’s most haunted castles – Leap Castle in County Offaly, Ireland – on June 1.
Footage from their visit shows the camera focussing on a mirror in the building.
Lisa – behind the camera – says: “Here it is, you can see him clearly, he’s moving back and forth.
“Do you see him?
“He’s moving again: ‘Hello’.
“He has a nose and is wearing a hat.”
Lisa then spots what – she claims – is a “beautiful young child”.
Lead investigator Siobhan sent the clip to the Irish Mirror and said: “One of our guests on the night was recording the mirror because we had seen it the week previous and we caught it in camera.
“If you watch the mirror you will see the man coming back and forth on demand, we have named it ‘The Man in the Mirror’.”
While those inside the spooky castle were convinced the “figure” was proof of a ghost, the movement of it in relation to the cameraperson could indicate it is simply a reflection of the camera’s light.
But it is not the only “ghost” video to have emerged online in recent weeks.
A daughter was convinced she captured the ghost of her dad walking her dead dog on her CCTV.
