An investigation to find four men has been launched after the group broke into a Cambridgeshire supermarket and stole a safe.
The masked men entered the Budgens store in Sugar Way, Peterborough at around 2am on Wednesday, June 5 before fleeing in a black Audi A4.
Police detectives are appealing for any witnesses or anyone with information to come forward to help with their search for the men.
Officers, including those trained in forensics, have attended the scene and an investigation is ongoing. No arrests have yet been made.
Detective Inspector Tom Rowe said: "We're keen to hear from anyone who saw any suspicious activity in the area last week.
