Two men wearing balaclavas and carrying a handgun burst into the home of Francis Kelly at Yeats Avenue, Carew Park on Saturday night.
Mr Kelly was badly beaten in the struggle and was treated in the Mid-Western Regional Hospital. He was later allowed home from hospital.
Two elderly uncles of Mr Kelly were in an upstairs room at the time of the assault. The incident happened at around 9.30pm and gardaí at Roxboro are appealing for anybody who may have been in the Yeats Avenue area on Saturday night to contact them.
There is increasing garda concern at an ongoing feud between members of the Kelly and Casey families. The Kellys live in Southill and the Caseys are based in Clonlong Halting site, adjacent to Southill.
The previous weekend, another member of the Kelly family, Anthony, who ran the A&E security firm with the late Mikey Kelly, had a miraculous escape after his car was hit by at least eight bullets as he drove home after dropping his children to school. One bullet went through the head rest of the driver’s seat. Gardaí said a semi automatic handgun was used in the attack.
Mr Kelly said afterwards that he saw two men with balaclavas coming towards his car and one opened fire at point blank range.
Mr Kelly was hit by gun pellets earlier this year in another attack near his home. Two members of the Casey family have also received serious injuries.
One had the side of his face blown away when a device, used by vets to put down animals, was put to his head. In another gun attack, a teenage boy survived being hit in the head by a bullet.
Extra garda patrols have been placed in the Southill area in recent weeks amid rising tensions between the two groups.
