A 20-year-old man who was seriously assaulted in Tallaght yesterday has died in hospital.

He was attacked on St Dominic's Road at about 4 am on New Year's Day - and had been on life support.

Gardaí have arrested two men in connection with the assault this afternoon - they're being held at Rathfarnham and Tallaght Garda Stations.

Their arrests follow the violent disorder charges brought against 23-year-old Graham Palmer of Bolbrook Grove and 20-year-old Aisling Burke of Homelawn Road earlier today.

Meanwhile, a fifth person arrested late last night still remains in Garda custody.
