An investigation has been launched into the discovery of 140,000 euro stashed under a bath in the former home of a one-time IRA hunger striker-turned-property tycoon.
The six-figure cash haul was found by a plumber working in the property - which was repossessed last year from bankrupt-billionaire Tom McFeely.
The Criminal Assets Bureau (CAB) was alerted following the discovery at the mansion on the affluent Ailesbury Road in Ballsbridge, south Dublin, according to the Irish Independent.
An investigation is now under way, with CAB officers trying to determine who the legitimate owner of the money is.
Mr McFeely served 12 years in the Maze Prison for shooting an RUC officer in Derry and spent 53 days without food during the 1980 hunger strikes.
But he has remained in the media spotlight over the years - most recently having been embroiled in a court case involving the controversial Priory Hall development in Donaghmede, north Dublin.
Some 65 families were forced to move out of the complex in October 2011 after experts deemed it a fire hazard and a string of construction defects were found.
Fiachra Daly, a former resident, took his own life in July.
His partner Stephanie Meehan has said he had been under stress following the evacuation from their home.
Mr McFeely, originally from Derry, avoided going back behind bars last July after successfully overturning a contempt of court judgment.
The developer appealed against a judgment that he broke court orders.
He had been ordered by the High Court in Dublin to carry out remedial w orks at Priory Hall, but was sentenced and fined when he did not.
Barristers for Mr McFeely appealed it was impossible for their client to comply with orders because he had been evicted from the site.
The state's bad bank, the National Assets Management Agency (Nama), took over Mr McFeely's Ballsbridge mansion after he was declared bankrupt last summer.
It was placed on the market at three million euro - just a fraction of previous valuations of around 15 million euro.
The house was sold and renovations are now under way.
Mr McFeely has claimed in the past that he has bank debts in excess of 200 million euro.
