The employees complied with the man’s demands and he fled on foot from the premises with a sum of money.

The male staff member was treated at the scene for the injury to the back of his head.

The man was described as approximately 185cm tall with a slim build and was wearing blue/grey track pants and jumper with a black beanie covering his face.
