Two men wearing motorbike helmets, one armed with a crowbar, stole a till and cigarettes from a Co-op in Northamptonshire
CCTV images of the men, who entered the Co-op in Northern Way, Wellingborough, at about 10.40pm on Tuesday, March 10, have been released by Northamptonshire Police.
The robbers told the shop workers to lie on the floor while one of the men took the till and the other took cigarettes from behind a shutter.
They then put the cigarettes in a bag they had taken with them and fled.
Both men were white and were wearing distinctive motorbike clothing.
The one who was carrying the crowbar wore a blue and white helmet, motorbike gloves and a dark blue jumper.
The second man wore a red and black helmet and a dark padded motorbike jacket.
Witnesses, or anyone who recognises the two men from the CCTV stills, can call Northamptonshire Police on 101.
