A GARDA manhunt was continuing today for a 32-year-old suspect after officers raided his apartment and seized a large quantity of crack cocaine and eight shotgun cartridges.
The cache was found in the Finglas area of north Dublin on Tuesday night.
Meanwhile, in a separate raid, a woman was arrested after gardai found €150,000 worth of heroin in a house in Ballyfermot last night.
Sources said that the suspect in the crack cocaine case is aware that gardai from the Ballymun drugs unit raided his apartment and discovered the haul, but officers have yet to find him.
No one was in the upmarket property when it was raided by gardai investigating crack cocaine dealing.
Sources said that crack cocaine is becoming more prevalent across the city and a number of very serious criminals are involved in dealing it.
"When this fella is lifted, he will have questions to answer as there is evidence linking him to the stash," said a source.
As far back as March 2011, Fr Peter McVerry, the well-known social issues campaigner, said that the drug of choice in Ballymun - where he lived at the time - was crack cocaine.
His comments came as he was addressing a conference in Dublin Castle marking the 30th anniversary of the founding of Ballymun Youth Action Project, the State's longest-running community drugs project.
The fact that crack cocaine is smoked rather than snorted or injected has contributed to its popularity. Its effects are felt more quickly and are more intense than powder cocaine.
Medical experts say crack is more dangerous than other drugs because it is inhaled and carried swiftly into the brain.
Elsewhere, a significant haul of heroin was seized in Ballyfermot.
Officers from Clondalkin Garda Station raided a house and a woman in her 50s was arrested at the scene.
She is currently being detained under Section 2 of the Criminal Justice (Drug Trafficking) Act, 1996.
Gardai estimate that the heroin seized has a street value of €150,000, pending analysis.
A garda spokesman said: "These operations use advanced analytical and intelligence methods to disrupt criminals and dismantle their networks.
"Drug seizures play a critical role in targeting the livelihood of criminals and reducing their ability to carry out illegal activities."
