The Criminal Assets Bureau is examining the beneficial owners of a home in North Cork and another in South Tipperary as part of an ongoing money laundering investigation.
In a series of searches this morning, CAB targeted four sites and froze around €40,000 in a bank account.
In a statement, the CAB said: “The search sites consisted of two homes in Dublin 15 and Dublin 6, and two professional premises located in Dublin 2 and Co Laois.”
It said bureau officers were supported by the elite Emergency Response Unit, local gardaí and officers from the Garda National Immigration Bureau.
During the course of the search, documentation, phones and electronic devices were seized. They will be analysed by specialist CAB analysts.
The statement said: “Approximately €40,000 has been frozen in an account in a financial institution pursuant to Section 17 of the Criminal Justice (Money Laundering and Terrorist Financing) Act, 2010.”
It said the search operation was "a significant development in an on-going operation targeting an organised crime gang involved in the cultivation, sale and supply of controlled drugs".
“CAB are investigating the beneficial ownership of a home in South Tipperary and another home in North Cork.”
