Police have released a CCTV image of the moment a masked raider threatened a shop worker with what appeared to be a pistol.
Darren Campbell, of Aspen Crescent, Houghton Regis, Bedfordshire, has been jailed for more than four months by a judge at Luton Crown Court after admitting a number of offences.
The image shows Campbell, 37, at a newsagent in Dunstable in June, dressed in black and wearing a black horror mask.
A detective who investigated the raid said Campbell subjected his victim to a “terrifying ordeal”.
