Senior gardai say they're confident they'd be able to respond to a terror attack in Dublin within 8 minutes. They looked at in on paper over the weekend, following the London Bridge attack which has now claimed eight lives.
Assistant Commissioner John Twomey said "We did a paper exercise to see what our response capacity would have been at the same time to the incident in London."
"We are happy that we would have had nine armed units in the vicinity of Dublin City Centre and we are happy our response would have been of a similar time to that in the UK", he said.
Meanwhile, Armed officers are surrounding a Garda Station in Wexford as a man's being questioned over the London attack.
He was arrested at a business premises in Wexford Town yesterday afternoon over suspected links to terrorist Rachid Redouane who had lived in Rathmines for a time and travelled back and forth between the UK and Ireland.
Reporter for South East Radio Jimmy Gahan said: "We understand that the name of this man emerged after documents found on or near Rachid Redouane following the attack, named him as a possible suspect."
He added: "He was taken to Wexford garda station and he is being detained there as we speak. We do know he isn't married, he's in his early 30s and has been living in Wexford for some time."
He's the second person taken into custody in Ireland over Saturday's atrocity.
The first man, a Moroccan was arrested at a property in Limerick on Monday night. It's suspected that ID documents found at the house were linked to Redouane.
Gardai have confirmed they arrested a man under the Theft and Fraud Offences Act. He has since been released without charge and a file in being prepared for the DPP.
