Gardai are questioning a man on suspicion of dangerous driving after a man was hit and killed in a crash near Derry's border with Donegal.
At around 11.55pm a silver Opel Omega car collided with two pedestrians in Brigend.
It's believed the car was traveling from the Derry direction towards Bridgend prior to the incident.
One of the pedestrians, a man in his 20s, was later pronounced dead at Altnagelvin Area Hospital.
The second - who is also a man in his 20s - was not seriously injured.
The driver of the car, a man in his 30's, was arrested at the scene on suspicion of dangerous driving - and is being detained at Buncrana Garda Station.
The road remains closed and diversions are in place.
Gardaí are appealing for witnesses to the incident to contact them.
They're particularly interested in hearing from a couple who flagged down a Garda patrol car at a filling station in Brigend and reported the crash.
Investigations are ongoing.
Sinn Fein Councillor, Caoimhe McKnight says the community is heartbroken, "the community are completely shocked and saddened, especially on a day like today when there's lots of families celebrating their mothers, but this man was at a christening yesterday."
