Gardaí in Limerick were yesterday investigating two separate shooting incidents in the city in the early hours of Sunday morning.
No one was injured in either of the attacks.
A spokesman for the Garda press office said the first incident occurred at Delmege Park, Moyross, at 4.10am.
"A number of shots were fired at a house causing damage to the front sitting room window and the front door," according to a Garda statement yesterday.
The second incident occurred at Lenihan Avenue, Ballinacurra Weston, at 5.45am, when two shots were fired through the front window of a house.
Both scenes were preserved and examined by Garda technical experts yesterday morning and gardaí are continuing their investigations.
The shootings are the latest in a series of violent incidents in the Limerick city area within the past week.
Last Monday, a 26-year-old man was hospitalised after he was shot at a local soccer pitch in the Janesboro area of Limerick.
The injured man was hit in the knee but his injuries were not life-threatening.
On the same day, the body of 33-year-old scaffolder Patrick Coleman was discovered shortly after 1am when gardaí were called to his home in John Carew Park, Southill.
Mr Coleman, who was originally from Co Kildare, was attacked about 90 metres from his home as he returned from a night out in Limerick city. Three teenage boys later came forward to help gardaí with their inquiries.
None of the teenagers who presented themselves to gardaí were arrested, but gardaí described their coming forward last week as a "significant development" in the investigation.
They said they expected to send a file to the Director of Public Prosecutions in the coming weeks.
