"This is a sad day for Ballyfermot,” Cllr Doolan, chairperson of the Joint Policing Committee, said
Cllr Daithí Doolan was speaking after a woman was arrested and brought to Clondalkin Garda Station where she is being quizzed about the fatal assault.
Emergency services were called to an incident in Claddagh Court shortly after 2.30am.
Sources say the victim, who was in his 30s was “found unresponsive” when gardai arrived.
There were two other people present in the flat as well as the suspect aged in her late 40s and the victim.
These two people have been interviewed by gardai who are not looking for anyone else.
The flat was sealed off as a crime scene as gardai and Garda forensics officers carried out further investigations.
"This is a sad day for Ballyfermot,” Cllr Doolan, chairperson of the Joint Policing Committee, said.
“This level of violence affects the whole community. My thoughts and sympathies are with the family of the victim.”
He added: "I would encourage anyone with any information, no matter how small or insignificant they believe it is, to please contact the gardaí."
The victim was not known to gardai for involvement in crime.
