Two Gardai are being treated in hospital after being shot in west Dublin.
The incident happened in Whitechapel Grove in Blanchardstown last night.
The officers were struck in the hand and leg - injuries which are said to be non-life threatening.
The incident led to a standoff and there was a media blackout for several hours.
One man was arrested and is being held at Blanchardstown Garda Station.
Taoiseach Micheal Martin says he was shocked and deeply concerned to learn about the shooting of two on-duty Gardai, and has wished them a speedy recovery.
Garda Commissioner Drew Harris has commended the officers involved for bringing the incident to a successful conclusion, while the Justice Minister Heather Humphreys says the incident is a reminder of the dangers officers face each day.
The shooting comes just three weeks ahead of the first anniversary of the death of Charlestown native Detective Garda Colm Horkan, who was shot and fatally injured while on duty in Castlerea on 17th June 2020.
The 49-year old, who was based at Castlerea Garda Station, died after being shot while responding to an incident.
