RTÉ News reports that the man who was killed in the Christmas Eve attack was the suspected gunman, 26-year-old Tristan Sherry.

It is believed that a father and son who were in Browne's Steakhouse on Main Street in Blanchardstown on Sunday evening were Sherry's intended targets, according to RTÉ News.

The restaurant was full of customers, including children, when the attack unfolded.

Taoiseach Leo Varadkar said that he was "shocked" to hear about the shooting in Blanchardstown and thanked gardai.

Shocked to hear about the shooting today in Blanchardstown in a well known family restaurant I’ve visited many times.

Full Garda investigation underway. My thanks to them and solidarity to staff and customers.

Ireland's Minister for Justice Helen McEntee said on Instagram on Sunday: “I deplore the violence in Blanchardstown tonight.

“This viciousness has resulted in unimaginable human suffering this Christmas.

“That anyone could perpetrate such violence as families gathered together is especially disgusting.

“I’m thinking of the bereaved, those who were at the scene and indeed all the emergency service personnel working tonight and over Christmas who have to deal with this senseless violence.

“I call on anyone with information of any kind to contact An Garda Síochána.”
