He set up cameras at the offices after councillors and council workers told of hearing voices and seeing apparitions – including one known as the Grey Lady.

Councillor Bill Boulter, who also appeared on the TV show, said: “The offices were featured in the investigation because of the things people have heard and seen over the years.”

Coun Boulter, who conducts walks and talks about the history of Wigston, said Bushloe House, where the authority is based, was built by Leicester architect Stephen Fry in 1850 for his own use, but he never lived here.

He said it was initially rented to a Rev Berry, and in 1866 was bought by Hiram Abiff Owston and his bride, Elizabeth Walley Varley, of Stanningley Hall, Yorkshire.

“There is a story that one of the children of the servants died after falling down a staircase at the house,” said Coun Boulter.

“I have heard a child crying near a staircase and I have heard children’s voices, too.”

The ghost-busting session took place from 10pm until 2am. Viewers did not see conclusive proof there were any spirits at the house.

However, Don is seen reeling after he says he has been “blasted into last week” by a spirit presence.

Coun Boulter said: “I think there is something that can’t be explained by our knowledge.”

Don said his own team had filmed the session at the house, as well as the TV crew, and had picked up more sound and voices than the television team.

He said: “There are definitely spirits there. I was picking up the spirit of a woman, but I don’t know if it was the Grey Lady, whoever she is.

“I would like to go back, because on that night it was rainy and cloudy and the bad atmosphere affects the effective communications of the spirits.”

Ann Court, director of services at Oadby and Wigston Borough Council, said she had been contacted by Don about filming at the house with a TV crew.

“All he wanted was to see if he could make contact with any spirits,” she said.

“There have been some reports of staff hearing and seeing things but no-one has suggested they ever feel threatened or upset by them. I do not believe in ghosts myself.”
