A man died in hospital today after a road crash in which the driver was arrested for drink-driving.
The 22-year-old is the third person to die on the country's roads this weekend and the 42nd road death of the year.
Gardaí said he was a passenger in a car which crashed at 1.15am at Derrypatrick Grange, Dunsaney, Co Meath.
Three men, two passengers and the driver, were injured and taken to Navan Hospital for treatment where the 22-year-old died hours later.
The second passenger, a 23-year-old man, remains in a serious condition.
The Garda Press Office said the driver, also 23, was arrested on suspicion of drink driving and was questioned at Trim Garda Station.
He was subsequently released pending a full investigation of the circumstances of the collision.
