The death of Detective Garda Colm Horkan is "an all-too-painful reminder of the personal risks that Garda members take", the Dáil has heard.
The chamber took time this morning for statements of sympathy to be placed on the record, with Justice Minister Charlie Flanagan leading the tributes.
Mr Flanagan said that Garda Horkan's death was a reminder of the dangers of the job, with 89 gardaí now having lost their lives in the line of duty.
"Detective Horkan’s death is an all-too-painful reminder of the personal risks that Garda members take, while working to keep us safe.
"While grounded in our communities, they courageously take on the burden of standing between us and danger. It is to them that we turn in times of crisis, including during the current pandemic."
Roscommon TD Denis Naughten said that June in Castlerea would usually be "ball-hopping month - Connaught football month".
"This year, there is no football banter. Every member of An Garda Síochána is doing their bit for people cocooning in an area of rural Ireland where people are physically and socially isolated at the best of times.
"This year in Castlerea the football banter was replaced by the shocked silence which reverberated across this country, in fact across the globe.
The Labour Party's Ged Nash said Det Garda Horkan was "an integral part of his community and the first to put up his hand when something needed to be done", while Fianna Fáil's Jim O'Callaghan said that the country can "gain some courage" from the "outpouring of grief across the country".
Mr O'Callaghan said this showed the high regard in which An Garda Síochána is held.
Sinn Féin's Martin Kenny said that "the people of that (Roscommon and Mayo) have lost a loyal friend, the Garda has lost a brave colleague and their immense pain is unimaginable The Justice Minister said that he was aware that the statements would not ease the pain felt by the Horkan family, but he hoped that the high regard in which he was held would bring them some comfort.
"I know that our statements today cannot ease the pain the Horkan family is feeling for their fallen son, brother, cousin and uncle. But I hope they can take some comfort in the obvious respect and admiration for Colm that we saw in Charlestown on Sunday; and in the way that the whole country united with An Garda Síochána, with communities everywhere standing in silent tribute with their local Gardaí, to honour Colm as he was laid to rest."
