TRIBUTES to fallen hero Detective Garda Adrian Donohoe have continued to pour in from across the country.
Books of condolence have been opened in a number of venues while one judge paid tribute to the officer during a court sitting.
Chief Superintendent John Scanlan, a friend of Det Gda Donohoe's brother-in-law, said the murder "is one of those things that brings us all together as a police force".
In Dublin, a young man whose garda father was forced to retire when injured in the line of duty was among those who paid their respects.
A steady stream of people arrived at the Mansion House in Dublin's city centre to sign a book of condolences.
Lord Mayor of Dublin, Naoise O Muiri, was the first to sign the book when it opened.
"It's a very sad occasion and we want to show support for the family," Mr O Muiri said.
Assistant Garda Commissioner John Twomey was the second to sign. He said it was a very sad time for the family of the officer.
Among those who came to pay their respects were a large number of the detective's garda colleagues. "Duty to the end," one wrote in tribute.
The book was open between 2pm and 5pm yesterday. The public will also have an opportunity to sign it between 10am and 5pm today and from 10am until 8pm tomorrow.
Books have also been opened at Det Gda Donohoe's Dundalk station and elsewhere.
Hugh McGowan, from Co Limerick, said that he came from a garda family which included uncles who undertake the same kind of work as the detective.
"As a country, we have to support the gardai," Mr McGowan said.
He was saddened and shocked by the brutal shooting and called the men who took part in the incident "cowards". He added: "The killers didn't even give him a chance."
Mr McGowan's father retired around 10 years ago after he was injured in the line of duty.
Two councillors on Drogheda Borough Council, one a former detective garda, have opened a credit union account to create a fund that they say will be made available to assist and support the gardai investigating the murder.
Fine Gael councillor Richie Culhane, a former member of the Special Branch, said the killing "is an attack on the entire community and a dedicated public servant has lost his life defending his fellow citizens".
He and party colleague Kevin Callan, a practising barrister, opened the account at Drogheda Credit Union yesterday.
Meanwhile, Judge Mary Ellen Ring expressed her sympathies to the murdered man's colleagues before a sitting of the Dublin Circuit Criminal Court .
She said she wanted to "express the sympathy of the court" to those close to the garda.
Offaly County Council's joint policing committee observed a minute's silence in honour of the detective.
