Explosives and a substantial quantity of heroin have been found by gardaí investigating organised criminal activity in Co Louth.
Gardaí found four viable improvised explosive devices and other material used in the manufacture of explosives when they searched a derelict building near Castlebellingham.
Heroin with an estimated street value of €45,000, a sawn-off shotgun and a number of cartridges were also seized in the operation.
The Defence Forces deployed the Explosive Ordnance Disposal (EOD) team following a request by gardaí. An examination was carried out and the devices have been removed for technical and forensic examination.
