A house on Lenihan Avenue in Ballinacurra Weston, Limerick remains sealed off as gardaí continue their investigation into the fatal stabbing of a man in the city early this morning.
The man was found with stab wounds at the front door of a house at 12.35am.
Ambulance personnel alerted gardaí to the incident and the victim was pronounced dead at the Mid Western Regional hospital a short time later.
He has been named locally as 43-year-old Gerard McMahon, a single man whose family lived in the nearby Raheen Square area of Ballinacurra Weston.
Gardaí say they are keeping an open mind about the motive for the killing.
The victim was known to gardaí and had been before the courts on a number of charges in the past, including a number of burglaries and criminal damage.
Gardaí are investigating if his criminal past is connected to his violent death.
State Pathologist Dr Marie Cassidy is due to carry out a post mortem on the victim later today and an incident room has been set up at Roxboro Garda Station.
They are appealing for information and for anyone who witnessed activity at or near the house last night to contact them.
Mayor of Limerick Cllr Jim Long, who also knew the dead man and his family, has made a direct appeal to those responsible to come forward and assist gardaí in their investigation.
