An investigation is under way following a fatal crash in Clondalkin in Dublin last night.

A 15-year-old boy was seriously injured when the car he was travelling in as a passenger mounted a footpath and hit a tree at around 10pm at Station Road in Clondalkin.

He was taken to Tallaght Hospital where he was later pronounced dead. A post-mortem examination is to be arranged.

The four other occupants of the car, all male aged between 14 and 16, suffered non-life-threatening injuries.

One of the boys was taken to Our Lady's Hospital for Sick Children in Crumlin, where his condition is said to be serious.

The other three have been taken to Tallaght Hospital.

All of the teenagers involved in the crash are from the Ballyfermot and Cherry Orchard areas of Dublin.

The scene was closed to facilitate a forensic investigation but has since re-opened.

Efforts are underway to establish the history of the car involved in the incident, which gardaí say had not been reported stolen.

Gardaí are trying to establish whether or not someone sold the car to the youths sometime prior to the fatal crash.

Anyone with information in relation to the collision is asked to contact Ronanstown Garda Station on 01-666-7700, The Garda Confidential Line on 1800-666-111 or any garda station.
