A suspected crime boss is one of two men still being quizzed by gardai after a series of house searches and arrests.
The 32-year-old was held after detectives investigating last weekend's tiger kidnapping in Clondalkin swooped on properties in west Dublin, Meath and Kildare.
He was one of eight people who were held after a series of searches, in which quantities of cash were recovered and a number of cars taken away for forensic examination.
He is still being held at Terenure as his detention time was extended yesterday in the District Court.
Files are being prepared in relation to those released for consideration for prosecution by the office of the Director of Public Prosecutions.
One of the detainees is a woman who is supected of involvement in supplying a car during the €300,000 tiger plot, in which AIB Clondalkin bank manager Tony Walsh and his wife were held in their Templeogue home.
The man in custody is suspected of organising this latest tiger kidnap, as well as a previous one in Irishtown.
It is understood that further searches are taking place in the hunt for the weapons used in the last raid -- a sawn-off shotgun and a handgun.
The Garda operation was led by officers from the Dublin South division, with support from the Organised Crime Unit and the Emergency Response Unit.
Those held were taken to Crumlin, Terenure and Rathmines Garda Stations.
