Port Phillip Crime Investigation Unit detectives are seeking public assistance to help identify a man following a burglary at a Melbourne construction site earlier this month.
It is believed a man has gained entry to a construction site on St Kilda Road about 4.30pm on 15 November.
The man has then looked around multiple levels within the building.
A number of power tools and copper wire were stolen from the site, valued at $300,000.
The man is described as having a thin build, with black coloured pants, white and black shoes, a black backpack, hi-vis vest, black cap and gloves.
Investigators have released CCTV footage and images of the man they believe may be able to assist them with their enquiries.
Anyone who knows the identity of the man or who witnessed any suspicious behaviour in the area between 13 and 16 November is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
