A teenage boy has died after a suspected hit-and-run incident in north Dublin.
A man was later arrested in connection with the fatal collision on the R139 at Coolock.
The boy, aged in his early teens, was struck by a car at around 9.35pm on Saturday.
He was taken to the Children's University Hospital at Temple Street where he was later pronounced dead.
Gardai said the car involved in the collision failed to stop or remain at the scene.
A Garda spokesman said it was located and seized a short time later, close to where the collision happened.
A man, aged in his mid-20s, was later arrested in connection with the investigation.
He has been detained at Finglas Garda Station under Section 4 of the Criminal Justice Act 1984.
The R139 was closed to facilitate a forensic examination but has since reopened.
Gardai are appealing for witnesses and anyone with information to contact them.
