Moorabbin Crime Investigation Unit detectives are investigating following a burglary at a Carnegie Shopping centre last month.
Investigators have been told the victim closed the kiosk at the Kooyong Road shopping centre at 6pm on 29 January.
When he returned the following morning, he discovered the kiosk had been broken into and various mobile phone accessories had been stolen.
Investigators have released CCTV footage of a man who they believe can assist with their enquiries.
The man was perceived to be Caucasian in appearance and was wearing blue Calvin Klein t-shirt, shorts, and was carrying a black sports bag.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report at www.crimestoppersvic.com.au.
