Gardaí are appealing for witnesses after a man who was found with serious injuries at a Dublin apartment over the weekend later died.
Officers say the fatal assault is understood to have happened sometime between Saturday and the early hours of Sunday morning.
Gardaí were alerted by paramedics to reports of a man in his 30s with serious injuries at an apartment in Lucan at around 3am on Sunday.
He was taken to Connolly Hospital Blanchardstown for treatment, and died yesterday evening.
They say the man travelled via taxi from the Allenton area in Tallaght to an address in the Shackleton area of Lucan in the early hours of Sunday morning.
Anyone who was in either of those areas is asked to come forward.
