Police have released CCTV images as they investigate a couple of break-ins at Coles supermarkets in the Hunter, believed to be linked.
The first incident happened at Fletcher Village at about 1:30am on Friday January 12, while the second break-in occurred at Kurri Kurri at about 1:30am on Thursday April 19.
In both cases a group of about four people forced their way in, using sledge hammers, block splitters and crowbars before making off with cash.
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 appears to be a dark blue dual-cab ute. The second is a white sedan.
Anyone who recognises the people or the vehicles is urged to contact Crime Stoppers on 1800 333 000.
