GARDAÍ have seized £280,000 worth of suspected heroin as well as a number of offensive weapons following searches in Dublin.
The items were discovered during a search of a number of properties in Dublin 8 on Friday.
The 2kg of drugs will be sent to Forensic Science Ireland for analysis.
Gardaí said the operation was part of an ongoing investigation into the sale and supply of drugs and criminal activity in the Dublin 2 area.
The search was assisted by the Armed Support Unit, the Street Crime Unit, the Divisional Crime Task Force and gardaí attached to Operation Citizen.
No arrests were made during the search operation and investigations are ongoing.
'Significant seizure'
Also on Friday, gardaí arrested three people and seized €390,650 in cash during searches in Dublin and Portlaoise.
A large quantity of cash was initally seized after gardaí with the Garda National Drugs and Organised Crime Bureau (GNDOCB) stopped two vehicles on Friday evening in West Dublin.
A man in his 40s and another in his 60s, as well as a woman in her 50s, were arrested and detained at a garda station in north Dublin.
Follow up searches in Dublin and Portlaoise led to further cash seizures.
"I wish to thank all the officers involved in the operation which led to this significant seizure of cash," said Assistant Commissioner Justin Kelly.
"Seizing cash from organised criminal groups not only removes their ill-gotten gains but also deprives them of money they would have used to fund further criminal activity, which harms our communities."
