Do you know the knife-wielding man in the images?

He escaped with a sum of money and was last seen running west along Shore Street.

The employee was not injured.

The thief is described as being of Caucasian appearance, about 175cm tall with a solid build and was wearing a dark grey balaclava, a blue checked flannelette shirt, blue jeans, brown runners and white gloves.
