More than 100 Gardaí are carrying out a "major search and arrest operation" in Dublin's north inner city.
Thirty people have been arrested by Gardaí targetting the sale and supply of drugs in the sweep codenamed "Tempest".
It follows a six-month covert operation prompted by feedback from residents who were interviewed by Community Gardaí.
Gardaí from the Bridewell, Mountjoy and Store Street Garda Stations worked with the Garda National Drugs Unit in the operation.
Chief Superintendent Patrick Leahy speaking from Mountjoy Garda Station today said: "This Operation is being led out by the Community Policing Gardaí attached to the North Central Division and is a direct response to community concerns identified during the door-to-door engagement by the Community Gardaí since January of this year.
"To date more the 8,000 residents of the North Inner City have been interviewed by Community Gardaí in an effort to provide a more community focused customer centred approach to policing in the area."
So far, 46 searches have been conducted and 30 people have been arrested and will be remanded to appear in Dublin's criminal court on Thursday.
