Inspector Barry O’Rourke yesterday said there was a good response from the public to requests for co-operation.
“Every single report we receive is being pursued. People shouldn’t hesitate to contact us,” he said.
Burglars have gained entry to unoccupied houses in daylight, or early evening. In one instance, they hit several houses in close proximity in a short space of time.
Some of the houses are in upmarket areas like Aghadoe, Countess Road and Ross Road, while rural districts east of the town, such as Lissivigeen, Minish and Clonkeen have been targeted.
The thieves have got away with cash, jewellery, items of glass and clothing and have used iron bars and other weapons to force entry to houses, usually through rear windows.
One theory being probed is that Eastern European criminals, working together with Irish criminals, may be involved in the robberies.
Killarney mayor Tom Doherty urged the public to back garda investigations. Councillors called for 20 extra gardaí for the area.
Independent councillor Donal Grady said people were “absolutely petrified” their homes would be broken into.
