One pedestrian has died and another one has been seriously injured after being struck by a car in Co Donegal.
Two men aged in their 60s were hit by the car on Lower Main Street in Letterkenny at around 3am on Monday.
One of the men died in Letterkenny University Hospital later on Monday.
The other man has been airlifted to Galway University Hospital for treatment.
The driver of the car involved in the incident – a male aged in his late teens – was arrested at the scene of the collision.
He remained in Garda custody on Monday afternoon.
The incident has been referred to the Garda Siochana Ombudsman Commission (GSOH) because of an earlier interaction between the driver of the car and gardai.
Gardai have appealed for witnesses to come forward.
They are also asking anyone with dashcam footage from the area of the Dry Arch Roundabout and Oldtown Road between 2.30am and 3.30am to make it available.
The St Patrick’s Day parade planned for Letterkenny on Monday was cancelled as a mark of respect.
