A 58-year-old man killed in Newry was shot number of times at close range as part of a possible feud, police say.
The shooting occurred in Ardcarn Park, a residential area, shortly after 18:00 GMT on Thursday.
The victim was pronounced dead at the scene. His name has not been released.
Police say one line of inquiry is that the shooting was part of a cross-border crime feud, possibly involving drugs, and a murder investigation has been launched.
The killing was a “brutal and a senseless attack on a defenceless man”, Supt Norman Haslett said on Friday.
He said the 58-year-old victim, who was a husband and father, crashed his car into a nearby property after the attack.
Earlier reports suggest the victim was shot a number of times as he stood behind his car.
