Victim of Dundalk shooting was Crossmaglen man James Hughes
The man shot dead in Dundalk in the early hours of Sunday morning has been named locally as James Hughes.
The 35-year-old was originally from Crossmaglen.
A man approached a taxi outside a house in Cluain Ard in Lis Na Dara, shortly after 04:00 GMT and fired a number of shots into the car.
The 48-year-old male driver and a 21-year-old female passenger were injured in the incident.
A 32-year-old man later presented himself at Carrickmacross Garda station, where he was arrested.
He is being held under section 50 of the Criminal Justice Act 2007.
Sinn Fein Crossmaglen councillor Terry Hearty knew Mr Hughes.
""This is a terrible tragedy to befall the Hughes family who also lost their mother suddenly earlier in the year," he said.
"James was an extremely well-known and popular young man and devoted father.
"He was involved in the local community through his lifelong association with Crossmaglen Rangers and he was a familiar face around the town with many many friends.
"I called to the family home on hearing the news and they are understandably shocked and devastated by this."
