One man is still in custody after €90,000 worth of drugs were seized in South Kilkenny.
It was after a Garda operation between Kilkenny/Carlow and Tipperary Drugs Units on Friday night.
They stopped and searched a car on the motorway near Knocktopher and found large quantities of heroin and diamorphine.
The man is being detained at Thomastown Garda Station under Section 2 of the Drug Trafficking Act.
A follow-up search on a premises in Carrick On Suir took place yesterday but there have been no further arrests.
