A teenager has died after crashing his bicycle into a pillar in Tallaght.
Gardaí said the young man was seriously injured in the crash in a residential area near Fortunestown Lane at around 10:30pm.
He was taken to Tallaght University Hospital where he was later pronounced dead.
No other vehicles were involved in the collision.
Gardaí carried out a forensic examination of the scene yesterday evening and are now calling for witnesses to come forward.
They are particularly interested in talking to anyone who was in the Mac Uilliam Heights area of Tallaght between 10pm and 10:45pm and may have camera footage.
