Over €1m worth of heroin was seized by gardaí in Co Limerick on Friday.
Several searches were carried out in Corbally and Clonlara as part of this operation, and gardaí recovered heroin with an estimated street value of €1.34 million during one search.
No one was arrested during the course of the search, and the drugs will now be forwarded to Forensic Science Ireland for analysis.
A further search took place at a separate location and gardaí seized €12,500 in cash.
A man in his 40s was arrested at the scene of this search and was taken to Henry Street Garda Station where he is currently detained pursuant to Section 4, Criminal Justice Act, 1984.
Gardaí attached to the Limerick Divisional Drug Unit carried out the searches. They were supported by gardaí from Mayorstone, the Regional Dog Unit and members of the Defence Forces.
The searches were part of Operation Tara and targeted the distribution of controlled drugs in the Limerick area.
Investigations are ongoing.
