A Garda has been injured after responding to a robbery at a business in Blanchardstown.
Officers responded to reports of a burglary shortly before 4 o'clock this morning.
Two members came across a man with a weapon, understood to be a knife, who became aggressive and threatening.
A Garda in his 20s was injured and was taken to Blanchardstown Hospital.
The weapon was seized along with 1,500 euro in cash - a man in his 30s was arrested.
A garda spokesperson says: "At approximately 3:45am this morning, Thursday 26th June 2025, Gardaí attached to Blanchardstown Garda Station responded to a report of a burglary occurring at a business premises in Dublin 15.
"At the scene, it was apparent to both Gardaí that a burglary had occurred and they called colleagues by radio for assistance.
"As they searched the premises, they encountered a male in possession of a bladed weapon who became aggressive and threatening. One male Garda sustained injuries.
"During the incident, a male in his 30s, was arrested and is currently detained under Section 4 of the Criminal Justice Act, 1984 at a Garda Station in Dublin.
"The bladed weapon was seized at the scene along with €1,500 in cash.
"The injured Garda, a male in his 20s, was taken to James Connolly Memorial Hospital for treatment.
"His injuries are not life-threatening. Garda welfare services have been made available to the Garda.
"The investigation is ongoing."
The Garda Representative Association says: "It is with real concern that we acknowledge yet another incident in which a young Garda was assaulted while carrying out their duties, this time during the arrest of an individual in possession of a knife in Blanchardstown.
"The male Garda received medical attention at Connolly Hospital and has since been discharged following treatment.
"I wish to commend my colleagues for their courage and professionalism in the face of such adversity. Attacks on members of An Garda Síochána are entirely unacceptable, and sadly, becoming far too common.
"This incident serves as a stark reminder of the risks our members face daily while carrying out their work."
