52-year-old father abused all three of his daughters from as young as four and often beat them with a leather belt hears, Tullamore Circuit Court.
Acts of abuse were carried out on all three of his daughters when they were as young as four.
The offences took place in the family home, in his car and at Castlerea Prison.
His daughters were barley in their teens when the abuse took place at Castlerea Prison.
An incident that took place in Castlerea Prison was when one of his daughters was sitting beside him and he placed his hands around her and felt her backside, before moving them around to feel her private parts.
Defense counsel Padraig Hogan agreed that because the man had undergone abuse himself it dose not excuse the acts that he carried out.
