The offender has cut wires to a cash register and stolen the register containing cash.
The man is perceived to be Caucasian in appearance, in his 40s with long hair tied in a ponytail.
He was wearing black track suit pants with a white stripe down each leg, t-shirt, vest, sunglasses on top of his head and carrying a messenger bag over his shoulder.
