An estimated €200,000 worth of heroin has been seized in a garda operation in the Southill area of Limerick.
The searches were part of the ongoing investigation into the murder of 24-year-old Thomas Moran last week.
Mr Moran's body was found outside a burned out house last Monday morning. A man who was being questioned in connection with the murder has since been released.
A firearm, a number of shotgun cartridges and stun grenades were also found during the same investigation.
Meanwhile in Co Westmeath, gardaí seized a quantity of cocaine with a potential street value of €250,000.
The find was made when a car was stopped and searched in the Kinnegad area, shortly before midnight, as part of Operation Anvil.
A man in his mid 20s was arrested and is being detained at Mullingar Garda Station, under the Drugs Trafficking Act.
