Paul Newman, who works as an electrician, carried out his prank on Saturday after putting on a surgical gown and a mask and a wig.
For his ‘chainsaw’, Mr Newman used a disc cutter with the blade removed.
The 34-year-old, who lives in the Abington Vale area, said all the groups of children who were scared by him received sweets afterwards and he said none of the parents, many of whom he knew, were unhappy about his actions.
He said: “I just thought it would be a bit of fun. I hid behind the car with the disc cutter, which did not have a blade in it and then when I moved the security light came on.
“I then stood in silhouette and the kids ran off screaming. There was a steady stream of trick-or-treaters from 5.30pm to 7.15pm.
“We made sure that all the kids got sweets afterwards and none of them were upset. A lot of them I knew as they are friends with my children.”
