Detectives at Fawkner Embona Taskforce are appealing for witnesses following an armed robbery at a milk bar in Fawkner on Sunday.

Police have been told a man entered the milk bar on Tyson Street and made demands for money just before midday.

It is believed the offender produced a knife and jumped over the counter when the attendant threw a chair at him.

The bandit attempted to open the till but was unsuccessful.

He grabbed cigarettes before fleeing the scene.

The offender is perceived to be of African appearance and aged 16-18 years old.

He was wearing dark sunglasses, a white hooded jumper with the word “Deluxe” on the front, black tracksuit pants, gloves and carrying a black backpack.

Investigators have released images of a man that may be able to assist with their enquiries.
