Survivors tried in vain to save the man.
A 26-year-old man died after the car in which he was travelling plunged into a canal in Cavan has been named locally.
Daniel Grimes, from Kilteel, Co Kildare lost his life when the car he was in with two other men entered the canal at Woodford River, near the Ballyheady Bridge, on the Ballinamore to Ballyconnell Road.
The incident occurred on Saturday at around 6.30pm, around 3km from the bridge. Two other men (20s) who were in the car at the time managed to escape uninjured.

The incident happened at the end of an unmapped road.
Gardaí are trying to establish the circumstances surrounding the incident.
A technical examination of the scene has been carried out and the road is closed to traffic with local diversions in place.
