A man feels convinced his sinister antique ventriloquist doll is haunted after CCTV footage showed it blinking.

Michael Diamond, 48, was given Mr Fritz, made by a prisoner at the World War II Stalag II-B camp which was formerly in Germany, three months ago.

And Mr Diamond set up a GoPro in the late-night hours on September 19 and 20, after noticing the doll's glass display cabinet kept opening.

At least once or twice a week, the door kept coming off its latch so he decided to set up the camera 'for fun'.

Over the two evenings, the doors to the striking-looking doll swung open.

Its heavy eyes, which were initially tightly shut, spring open, and the lips open as though the ventriloquist is wanting to say something, in the eery clip.

Mr Diamond said he 'got a weird feeling in [his] gut' which is 'hard to describe', after replaying the footage.

He is not scared of Mr Fritz but admitted how he is 'wary' of it and keeps it locked away in his 'freak room' full of collector's items. This includes taxidermy animals, skulls and ancient weapons.

Mr Diamond added how he gets 'emotionally attached' to his collections and the reason why is a 'million dollar question'.

While he is married to Sally and has two children, Amber, 19 and Caleb, 11, he wants to give his doll a permanent home.

'I have no idea myself. I don't even know where to start. There are no open windows in the room and no airflow. The door is on a latch so shouldn't just swing open.

He set up a GoPro camera over September 18 and 19 after noticing the door kept swinging open and to his horror, saw the doll blinking its eyes and opening its mouth when he watched the footage

'I have told Sally and Amber about it and they don't like it at all. To stop it from happening I've chained the box up and covered it in a blanket.'

The father-of-two speculates that the prisoner, who created the doll, worked as a ventriloquist before being taken prisoner at Stalag II-B.

This camp was one of the first Nazi concentration camps in 1933 for German communists and went on to become a prisoner-of-war camp for Polish soldiers from the Pomorze Army.

Mr Fritz was allegedly taken to America after the end of the war and was owned by an antiques shop in Myrtle Beach, South Carolina, before arriving in the UK.
