Police are investigating a theft from a liquor store in Brunswick late last month.
Investigators have been told a man entered the Sydney Road store about 2.25pm on 24 June.
He selected a bottle of alcohol and then proceeded to walk out via the front door without paying.
The man is believed to be aged in his 30s, approximately 170cm tall with a thin build.
He was wearing a black Adidas zip-up hooded jumper, black pants and a black and white striped beanie at the time.
Police have released images of a man they believe may be able to assist with their investigation.
Anyone who recognises the man or with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppervic.com.au.
