Police in Hamilton say they have had a number of calls after releasing images of two men suspected of carrying out three aggravated robberies.
They say a pistol was pointed at staff in some of the robberies, which took place at a superette, a TAB and a liquor store.
In each of the robberies, the men made off with money and other items.
Acting Detective Sergeant Andrew Mortimore says since the release of CCTV images on Saturday some people have called the police to say they think they know who the men in the photos are.
He says officers are now working through that information.
Police said on Saturday that they were concerned about the escalation of the attacks and believed if the attacks continued it would only be a matter of time before someone got hurt.
