A 16-year-old boy has been arrested over a hit-and-run collision which has left a woman seriously ill in hospital.
The incident happened on Canal Bridge at Osberstown in Naas, Co Kildare, at around 8.25pm on Friday evening.
Investigating gardaí say one car collided with another parked car and then struck a 51-year-old woman who was walking at the scene.
The victim's condition at Tallaght Hospital is described as "serious".
An abandoned car has been recovered in connection with the investigation and will be examined by Garda technical experts.
The 16-year-old was arrested on Saturday morning and taken to Naas Garda station, where he is being held under section four of the Criminal Justice Act.
The road was closed for a period of time to allow forensic experts carry out an examination but has since reopened.
Fianna Fáil TD James Lawless, a friend of the injured woman's family, described the family as "really decent, hard-working people".
He said the woman, who is married with three children, would undergo surgery in Dublin’s Tallaght Hospital tonight.
He said he understood her neck and spine had been injured, and that she had two broken legs and a broken ankle.
Mr Lawless said the woman had been walking a short distance from her home to a local pub to join her husband for a drink. As she was going over Canal Bridge, a car travelling at speed hit her and he understood she had been forced up against the railings.
A Garda spokesman said: “Investigations are ongoing, and gardaí are appealing for anyone who witnessed the collision, who may have been on that stretch of road between 8.15pm and 8.30pm or may have any information to contact us in Naas on 045 884300, the Garda Confidential Line on 1800 666 111 or any Garda station.”
