HAMILTON Police Crime Investigation Unit detectives have been appealing for public assistance after a safe containing a large amount of cash was stolen during a burglary in Coleraine last month.

Police have been told unknown offenders forced entry into a business on Robertson Street between March 22 and 24.

Once inside, it is believed the safe containing a large amount of cash was stolen from an office inside the premises.

Investigators believe a black Holden Commodore was seen arriving in Coleraine from the west around 4.30am on March 23.

It is believed the vehicle may have travelled from South Australia and may assist with the investigation.
