Gardaí indicated that Donal (Don) O'Callaghan of Churchfield Green in the city had conducted the largest and longest running known case of welfare fraud in state history.
The 58 year old- who made full admissions in relation to the charges- claimed the pensions of his dead parents Donald and Eileen from 1987 to 2020, defrauding the state out of over half a million euro.
The court had previously heard that O'Callaghan had a chronic gambling addiction for which he was seeking treatment.
Judge Helen Boyle adjourned the case until tomorrow morning to consider her position on sentencing.
