Two gardai are being treated in hospital after being shot in Blanchardstown.
It happened in Whitechapel Grove 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.
"I was shocked and deeply concerned to learn that two Gardaí were injured in the course of their duties this evening," said Taoiseach Micheal Martin in a statement yesterday.
"I wish both Gardaí a swift and full recovery, and I thank them for their service on behalf of the public."
My thoughts are with the two members of An Garda Síochána who sustained injuries while responding to an incident in Blanchardstown this evening, and with their families.

Justice Minister Heather Humphreys added to the remarks, urging people with any information to contact Gardai.
Garda Commissioner Drew Harris has commended the officers involved for bringing the incident to a successful conclusion.
A man has been arrested and is currently being held at Blanchardstown Garda Station.
