Detectives are investigating potential links between a number of break-ins at supermarkets in the Hunter region earlier this year.

The first break-in occurred about 1.30am on Friday, January 12 at Fletcher, and the second break-in occurred about 1.30am on Thursday, April 19 at Kurri Kurri.

During both of these incidents, a group of up to four people are seen to force their way into the premises’ using sledge hammers, block splitters and jemmy bars, and stealing cash.

As part of ongoing inquiries, detectives have released CCTV images and are appealing for information relating to the incidents, which they believe are linked.

The CCTV images depict two vehicles seen in the area at the time of the break-ins and a group of people outside the stores.

The first vehicle is depicted as a dark blue dual-cab utility and the second vehicle is depicted as a white sedan.

Police are urging anyone who recognises the people, or the vehicles depicted in the CCTV images to contact Crime Stoppers on 1800 333 000.
