The father of five children whose home in Drogheda in Co Louth was shot at last night said he was the gunman's intended target.
Two women and five children were in the house at Knockbrack Close when 15 rounds from a pistol were fired through the front window.
One of the bullets grazed a mother who was tending to her eight-month-old baby.
Her husband, who was not there at the time, claims his home was attacked because he won a bare-knuckle fight seven years ago.
Gardaí believe the attack is connected to an ongoing feud among members of one family within the Travelling community.
They have appealed for witnesses to contact them in Drogheda Garda Station on 041-9874200.
Officers say a car, believed to have been used in the attack, was found on fire a short distance away at Platin in Co Meath.
Gardaí believe four men ran from the vehicle, which was a grey coloured Kia Ceed.
