Gareth O'Connor (27) from Harelawn Avenue in Clondalkin, Co Dublin, passed away at about 5.30pm yesterday, almost 24 hours after being attacked.
The father of three was socialising with a group of friends, including his brother and nephew, when they became involved in a verbal altercation with another group.
The incident happened at about 8.45pm on Thursday evening at Cow's Lane, Temple Bar. Gardaí investigating the assault are interested in speaking to a number of people who they believe recorded the melee on their mobile phones.
A post-mortem examination will be carried out later today by the State Pathologist, Dr. Cassidy, at Dublin City Morgue.
It has emerged that after Mr O'Connor was struck, the 33-year-old man who allegedly punched him was attacked himself and knocked unconscious.
The man from the Hartstown area of Dublin was brought to St James's Hospital for treatment to severe facial injuries which may include fractures.
However, after being treated in the hospital, he was arrested at 4.15am and he was being held in Irishtown Garda Station.
He is well known to gardaí for previous incidents.
Another two men, aged 35 and 27, who are suspected of assaulting Mr O'Connor's attacker, were also arrested. And a fourth man from Killester who is an associate of the man who attacked Mr O' Connor was also arrested.
All four have now been released without charge.
