Shepparton Crime Investigation Unit detectives are investigating three suspected to be linked burglaries in the Shepparton area earlier this month.
In the first incident, an unknown man gained access to a store on Goulburn Valley Highway in Kialla by smashing a front window about 5.10am on 2 December.
Officers believe he attempted to access the electronics area but was unsuccessful.
The next day, it is believed the same man forced entry into a store on Benalla Road about 1.40am.
The man, armed with a small axe, smashed a glass display inside the business.
Investigators believe he stole a number of mobile phones and tablets worth approximately $5000, before fleeing the scene.
In the third incident, investigators believe the man used an angle grinder to force entry to store on Wyndham Street about 5.15am on 6 December.
The man, again armed with an axe, smashed a cabinet inside the store before stealing a number of electronic headphones and fleeing the scene.
Investigators have released images of a man who they believe may be able to assist with their enquiries.
He is perceived to be Caucasian in appearance with short brown curly hair.
During the first incident, the man was seen wearing a high visibility jacket, a face mask, and glasses.
In the second incident, the man was seen wearing a beige hat, a long sleeved dark blue shirt, a black short sleeved t shirt, black pants, and a face mask.
In the third incident, the man was seen wearing a black cap, a dark green jacket, blue jeans, and yellow face mask.
Anyone who witnessed the incidents, has CCTV, dashcam footage or any other information that can assist investigators is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au
