It’s believed a man used a hammer to smash the front entry glass door of a high-end clothing boutique in South Yarra at about 4.20am on May 12.

Police were told that more than $100,000 worth of designer ladies’ clothing, including cashmere coats and Linda blazers, were stolen.

The haul is believed to have been loaded into a supermarket trolley and then thrown in the back of a silver Ford Falcon ute.

The man then drove towards Yarra.

Police have released images of a man they believe may be able to assist the investigation.

They allege he has committed a number of other shop burglaries in the Merri-bek and Fawkner areas as well.

He is perceived to be Caucasian, aged in his 40s, and with a solid build.

He was seen wearing a black face covering and a black cap.
