A man entered Maddy’s Store on Church Road at 1.20pm on Friday September 3 and threatened the cashier demanding money.
He left with a quantity of cash, tobacco and alcohol and was seen to walk off in the direction of Low Leighton Road.
Officers have now released a CCTV image of a man they would like to speak to in connection with the robbery and said they hope someone may recognise him from his clothing.
