Two service station workers have been left traumatised after an armed robbery on the Antrim Road in Belfast.
It happened at around 10pm on Friday evening, when a man who was armed with a knife entered the shop.
The staff members tried to escape after he demanded they open the till.
The suspect grabbed one of them by the arm, leaving a mark, but managed to leave the premises.
Police said the suspect remained in the store and stole a sum of cash before leaving.
