The men needed to be caught to stop them committing another violent robbery and hurting more innocent members of the public in the process, the officer in charge of the investigation into the armed robbery of the Regent Night 'n Day store said yesterday.
Detective Sergeant Rob Hanna said police understood people might fear coming forward, but they could leave any information, anonymously, on the free Crimestoppers line 0800 555 111.
He yesterday issued new pictures of the stolen Subaru stationwagon police believe was used during the robbery. The car was stolen from Orr St, Concord, between 11pm last Saturday and 11am the next day.
It was located in Elm Row on Tuesday.
"Someone may have seen this vehicle in their street or at a friend's house during the day of Sunday."
Police also issued a picture of a witness they would like to speak to. He entered and left the store either during or shortly after the 12.30am robbery.
Det Sgt Hanna also urged Dunedin business owners to review their security systems and the amount of cash they kept on their premises, in light the "recent increase in robberies in Dunedin".
Police are still investigating two other robberies and two attempted robberies in the city this month.
In one robbery, a man allegedly held up a service station at knifepoint; in another a man, who allegedly implied he had a gun, robbed a Kiwibank outlet.
Three people have been arrested in relation to those incidents, but police inquiries are continuing.
