Gardaí are believed to be investigating whether the murder of a man in Dublin yesterday followed a row earlier in the night.
49 year-old Michael Tormey, who has no known links to crime, was gunned down outside his house on Thomand Road in Ballyfermot.
The father of two had been out socialising on Saturday night before being shot shortly after 5 o'clock yesterday morning.
People Before Profit Councillor, Hazel de Nortúin, said the community is in shock.
"There's somebody left today without a husband, a father, a friend."
She said the crime "definitely won't go unchallenged".
