A massive cash seizure by gardaí is being linked to the Kinahan cartel.
Two men were arrested in Naas, Co Kildare on Saturday night under money laundering and terrorist financing legislation.
It was part of a planned operation targeting organised crime.
Cash totalling €829,265 was seized during the course of the arrest.
Detectives are said to be looking into whether the money was set to be moved to the continent.
Follow up searches also took place in Lucan, Sligo and Kildare during which a €50,000 car was seized.
The two men, one in his 30s and the other in his 40s, have since been released.
A file will be prepared for the Director of Public Prosecutions (DPP).
