Gardai and army searching waste ground in Blanchardstown have recovered a gun and ammunition.
The search is connected to an ongoing feud in the Corduff area and is the latest in a series of intelligence led searches.
Gardai called in the engineering corp from the Defence Forces who were using metal detectors and other devices to search for the firearms.
A source has said that the search discovered a gun and ammunition - this has been sent for examination by ballistics experts.
A source said: “Tensions in Corduff and the surrounding area is at all time high. It is believed that the gun may have been stored ahead of an intended hit in the coming days.
“Gardai have not made any arrests but there will be forensic examinations of anything found.”
Tensions are high in the Corduff area, near Blanchardstown, after two months of feuding gang violence.
Violence has erupted in the area in recent weeks when a drug gang ruptured and spilled into open gun battles on the streets of the suburb.
