Detectives from the Melbourne Crime Investigation Unit are hoping to identify a man following a burglary in Docklands last month.
Investigators have been told an unknown man gained access to a secure carpark on Waterside Place about 11pm on Saturday, 27 March.
The man forced entry into a number of storage cases before stealing a suitcase and leaving on foot.
Investigators have released images of a man who they believe can assist with their investigation.
The man is perceived to be Caucasian in appearance, aged in his late 30s and was wearing a blue and grey 'LA' jacket, blue jeans and a grey baseball cap.
Anyone who recognises the man is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential crime report at www.crimestoppersvic.com.au
