A man has been charged after the seizure of more than half a million euros during searches in Dublin and Cavan.
Officers targeting large scale trafficking of controlled drugs and associated money laundering raided five premises on Monday.
Gardai seized at least €500,000 during the course of the intelligence-led operation.
A man, 38, was arrested and was being detained at Navan Garda Station on Monday night.
The suspect has since been charged and was due to appear before the Criminal Courts of Justice in Dublin at 10.30am on Tuesday.
Speaking on Monday, Assistant Commissioner O’Driscoll, Organised and Serious Crime said: "This operation demonstrates the continued determination of An Garda Síochána to target organised crime through stopping the flow of money suspected to be proceeds of crime and which provides the motivation for organised crime groups to trade in drugs."
A spokesman added: "On 28th June 2020, personnel attached to the Garda National Drugs and Organised Crime Bureau (GNDOCB) within Organised and Serious Crime, undertook an intelligence-led operation involving the targeting of members of an organised crime group (OCG) who are suspected to be involved in large scale trafficking of controlled drugs and associated money laundering.
"In the course of operational activity undertaken in Co. Cavan and the northside of Dublin city, a total of five (5) premises were searched, resulting in a quantity of cash, estimated to be not less than €500,000, being seized."
