“On Thursday 1st September 1977 at approximately 1am, I was on duty in my capacity as a policewoman, when I received a radio message to 284, Wood [sic] St, Enfield. I went to this address where I found a number of people standing in the living room. I was told by the occupier of this house that strange things had been happening during the last few nights and that they believed that the house was haunted.

Myself and another PC entered the living room of the house and the occupier switched off the lights. Almost immediately I heard the sound of knocking on the wall that backs onto the next door neighbour’s house. There were four distinct taps on the wall and then silence. About two minutes later I heard more tapping, but this time it was coming from a different wall, again it was a distinctive peal of four taps. The PC and the neighbours checked the walls, attic and pipes, but could find nothing to explain the knockings.

The PC and the neighbours all went into the kitchen to check the refrigerator pipes, etc., leaving the family and myself in the living room. The lights in the living room were switched off again and within a few minutes the eldest son pointed to a chair which was standing next to the sofa. I looked at the chair and noticed that it was wobbling slightly from side to side, I then saw the chair slide across the floor towards the kitchen wall. It moved approximately 3-4 feet and then came to rest.

At no time did it appear to leave the floor. I checked the chair but could find nothing to explain how it had moved. The lights were switched back on. Nothing else happened that night although we have later reports of disturbances at this address.”
