A Fianna Fáil councillor has said he believes that high-visibility policing in Dublin has made the city safer, but that assaults do have "profound impacts" on communities.
Cllr Rory Hogan was speaking following the death of a young man following an assault in the Grafton Street area in the early hours of yesterday morning.
The victim has been named as 21-year-old Qayyum Balogun.
Mr Balogun was found on Clarendon Street, which is located close to Grafton Street, in a serious condition at around 3am.
He was taken to St James's Hospital, where he was pronounced dead a short time later.
A 19-year-old woman was also assaulted during the incident and was treated in hospital for non-life-threatening injuries.
Speaking on RTÉ's Morning Ireland, Cllr Hogan said that the attack was a "deeply disturbing incident and one that nobody wants to see occurring on the streets of Dublin".
"Incidents like these have profound impacts not only on the victim's family but also on the wider communities," he said.
Cllr Hogan said gardaí were at the scene within minutes.
Asked whether people can believe that Dublin city is safe following the assault, he said it was difficult as "sometimes incidents like these occur", adding that "we need to be sure to separate the emotional reaction to an incident like this to the overall statistics."
He said the overall crime statistics in Dublin are down year on year and that the capital was becoming a "much safer city than what it was a number of years ago".
Cllr Hogan, who is a member of the local Community Safety Partnership, said the partnership will be ensuring the fatal assault is discussed at the next meeting with senior garda representatives and community safety partners.
"We need to understand whether there are any wider lessons to be learned and whether additional measures are needed to improve safety in the area," he said.
On reducing crime in the capital, Cllr Hogan said an option to be considered is one that has been trialled in the north inner city, that of Community Safety Wardens.
"It started in 2022 in the north inner city and it's basically a proactive and supportive approach to de-escalating events that traditionally lead to crises like this," he said.
He said that despite there being an overall improvement in crime trends in many areas, it does not lessen the tragedy of what happened yesterday morning.
Gardaí are continuing to appeal for witnesses, particularly anyone in the Grafton Street/Clarendon Street area between 2am and 3.30am on 1 June.
Anyone who may have camera footage, including CCTV or dash-cam, is asked to contact Pearse Street Garda Station on 01 666 9000, the Garda Confidential Line on 1800 666 111 or any garda station.
Meanwhile, a separate investigation is under way into the death of a man who swam across the River Liffey following a reported assault in the War Memorial Gardens in Islandbridge on Saturday night.
The man, who was aged in his 30s, has been named as Thomas Griffin from Ballyfermot.
He was treated by fire brigade personnel after swimming across the river to lands adjacent to Chapelizod Road.
He was then brought to St James's Hospital, where he died on Sunday.
Gardaí have said that the results of a post-mortem examination will determine the course of their investigation.
