Police are investigating a robbery which occurred at a fast food restaurant in Coburg last month.
Detectives have been told that a man entered the store on Sydney Road around 1.20am on 26 April.
The man approached the counter and told a female employee to place cash in a plastic bag.
She complied and the man took the bag and left the store.
He has been described as possibly Caucasian, approximately 175-180 centimeters tall with a solid build and pot belly.
At the time of the offence he was wearing dark pants, a dark long-sleeved Nike top and white runners.
The offender also used a white scarf and blue hooded top to help conceal his identity.
Police have released images of a man that they believe may be able to assist with their investigation.
