A shot was fired in the Moyross area of Limerick early yesterday morning making it the fourth shooting incident in the city since the weekend.
The shot was fired at the front door of a house in Pineview Gardens between 12 midnight and 1 a.m. The three occupants were not injured.
A garda said the occupants were not involved in any other incidents and believe the shooting was not connected to ongoing feuds.
Meanwhile, the widow of murder victim Mr Eddie Ryan, whose home was attacked on Monday night, said yesterday: "They want to kill me too. They're trying to wipe out the Ryan and McCarthy family.
"They won't drive me out of my home".
She told the Limerick Leader newspaper how shots were fired at the front wall of her house at Hogan Avenue, Killeely, at 10.40 p.m. as she was preparing her eight-month-old baby, Jamie, for bed.
"My 11-year-old Serina was asleep on the couch. I was sitting here with Jamie in my arms ready to put him to bed when the bullets flew in through the front wall of the house. I got an awful fright with the noise.
"This was the fifth attack on our house, but the others have been bricks. I know who they are and they're doing this because I'm Eddie's wife. They think I'm frightened of them, but I'm not."
She revealed that the house shot at in Canon Breen Park in Thomondgate, also on Monday night, is where her late husband's cousin, Mr Paddy O'Halloran, lives. Another house shot at on the same night in O'Callaghan Avenue is where her sister-in-law, Ms Marian McCarthy, and her husband, Patrick, live.
The house at St Lawrence Park, Garryowen, which was attacked with bricks on Saturday night, is that of her sister, Ms Ann Collins.
Mrs Ryan said the feud has been going on since her husband was murdered in November 1999. "My kids are nervous. My daughter, Serina, was being hassled out and about, but now she doesn't go out any more." She was assaulted outside Limerick City courthouse recently when she was headbutted by a man who subsequently was imprisoned for three months. Her 19-year-old son Edward was charged in relation to the same incident and received a month's imprisonment.
