Police have released a number of CCTV images from two armed robberies on the Mid North Coast, in the hope of tracking down those involved.

The men jumping the counter, and assaulting two staff members.

The second robbery occurred at Krambach in the early hours of July 8, leaving a 27-year-old with minor injuries after four males broke into a service station on The Bucketts Way.

Police are now hoping to speak with three men, who are described as being of Aboriginal or Torres Straight Islander appearance and of a slim build.
