A man in his 40s has been arrested after two suspicious objects were found in a house in Newcastle West, Co Limerick, last night.
He is being questioned at Newcastle West Garda Station.
The devices, which were later declared non-viable, were discovered in rented accommodation on Maiden Street in the town just after 10pm.
A number of local residents were forced to leave their homes and had to stay in a nearby hotel.
The street was sealed off by gardaí as a precaution, but has since been reopened.
Army bomb disposal personnel also attended the scene.
