Yarra Crime Investigation Unit detectives are appealing for help to identify a man following an aggravated burglary in Collingwood earlier this month.
Police understand the victim was sitting watching television when he saw a man coming in his back door about 10.20pm on Thursday 4 June.
The victim yelled out and the man fled.
The man is perceived to be Caucasian in appearance with short dark hair.
He was wearing a light-coloured tee shirt, dark pants and light-coloured Adidas runners.
Police have released CCTV and images of a man who they believe may be able to assist with their enquiries.
Anyone with information or who recognises the man is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au
