Up to four men are being sought following a robbery at the post office at the village of Caherconlish this morning.
Three raiders, one armed with a wheel brace and another armed with a sledgehammer, entered the post office just before 9.30am and demanded money.
It is understood the time-lock was in operation at the time and the raiders are believed to have gotten away with a small amount of money.
Gardaí believe a fourth raider may have been waiting outside with the getaway car.
Nobody was injured during the incident and the scene is now being examined.
A car suspected of being involved in the robbery was later located near O'Briensbridge in Co Clare.
Meanwhile, gardaí recovered a firearm and a substantial amount of cash, believed to up to €40,000, during the course of a search of two houses in the Ballinacurra Weston area of the city last night.
The search was part of an ongoing operation by gardaí investigating gangland criminality in the city.
Two men are in custody at Roxboro Garda Station.
