Detectives from the Port Philip Criminal Investigation Unit are appealing for public assistance following an aggravated burglary in South Melbourne last month.
It is understood a man entered a property in Coventry Street at around 2.40am on Thursday March 24 while the occupants were asleep.
Detectives learned that a male victim awoke to find the attacker and escorted him out of the building.
The assailant then fled and there were no injuries.
Investigators have released a digital image of a man and CCTV footage in hopes someone can recognize him.
The man is described as Caucasian, in his 40s with short brown hair.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or report to www.crimestoppersvic.com.auExternal link.
