GHOST investigators had a spooky experience when searching for things that go bump in the night in a North-East building.

Tony Liddell, of Leadgate, Consett, County Durham, and his team of six investigators stayed all night at the Assembly Buildings, which opened in Newcastle in 1776.

There have been sightings at the building of a ghost dubbed the Grey Lady, who is said to have thrown herself off the balcony.

The team set up their equipment on March 7 and settled down to see what the other world would bring them.

He said: "We had two camcorders physically switched off for no explainable reason and we have a photograph of a light ball above a table, the appearance of which coincided with a loud crash."

An archaeologist, historian and part-time paranormal investigator, he has scientifically investigated some of the region's most famous haunted buildings - with the findings catalogued in a book published last year, Otherworld North-East: Ghosts and Hauntings Explored.

Tony's second volume of Otherworld North-East, featuring the Assembly Buildings, will be published next year.
