It’s thought around 6,000 cigarettes were stolen. The driver wasn’t hurt.
The suspect has been described by police as around 6ft to 6ft 2in tall. He was wearing dark grey tracksuit bottoms, a dark coloured hooded top, and a baseball cap with a light coloured peak.
The mask he was wearing had no eye holes and could possibly have been a black stocking.
The force are asking for anyone who might be offered cheap cigarettes and are suspicious of where they may have come from to get in touch, or those in the area at the time of the robbery to contact them quoting reference 16/33434/19.
