Dennis Binks and his team of ghost hunters organised the ‘Hellnight’ event at the Hind Hotel in Wellingborough on October 31.
The hotel, which dates back to the 17th century and started out as a coaching inn, is where Oliver Cromwell is thought to have planned the Battle of Naseby and is believed to be haunted.
And Mr Binks of Corby said the stage was set perfectly for a ghost hunt on Halloween, including foggy weather that night.

He said: “We had some really good paranormal activity going on.
“In one room we were doing a human pendulum.
“One of the members of the public was aware of a little boy holding their hand.
“He led her to the back of the room and all of a sudden a handprint appeared on the window frame and the room was full of people who witnessed it.”
The event was a sell-out, with 40 people taking part in groups of 10 which went into different parts of the hotel.
Mr Binks said other activity they saw on the night included a chair moving on its own, contact from a dead relative of one of those taking part, and several people being aware of a white shimmer near to the spot where a little girl was murdered many years ago.
Mr Binks said: “A little girl died there, she had a sword put through her at the bottom of the stairs.
“The room next to it is now the restaurant.
“When she was alive, she didn’t like that room so she always wanted a light on.
“So for the nine years she was alive, she wanted it on, but we put it out.
“We were aware of a little white shimmer moving about, but only a couple of people saw it.
“It could have been a little white dress.”
Mr Binks said they have received some great feedback on Facebook about the event, and added: “A lot of people said it was the best ghost hunt they had been on.
“And we raised £525 for Macy’s Memory, which is a beautiful charity.”
Macy’s Memory supports families of children with a life-limiting illness from birth to the age of 18.
It was launched by Katrina Baker of Corby, whose daughter Macy died in March 2008 aged just 22 months.
The youngster had Patau’s syndrome which left her blind, deaf, with kidney and brain abnormalities and severe lung disease.
The charity can help with fees towards a funeral, headstone, last wish UK holidays as well as sensory toys and equipment.
Mr Binks is part of the Northamptonshire Paranormal Investigation Team, which meets at the St John Ambulance Hall in Corby.
