The incident happened at the junction of South Anne Street and Duke Lane Upper at about 03:00.

Another man in his 30s was seriously injured in the incident and is receiving treatment for non-life threatening injuries.

A murder investigation has began and the scene of the incident is still sealed off.

The incident occurred following a row between two groups of people who were out socialising.

Sinn Féin's justice spokesperson called the incident "deeply disturbing" and said it had caused great shock.

Matt Carthy said there was a "serious problem" in relation to public safety in Dublin city centre, and said that there are not enough gardaí (police) on the streets.
