Gardaí are investigating the alleged abduction and assault of a teenage boy in the early hours of this morning in Dublin.

A garda spokesperson said a 16-year-old boy was bundled into the boot of a silver Volkswagen Passat after he and friends were involved in an altercation with another group of males at around 5.30am in the Beaverstown Road area of Donabate.

The boy was released at around 9am near the M50 in the Clondalkin area and taken to Beaumont Hospital for treatment. He has since been released.

A ransom was demanded for the boy's release, but it is understood no money was handed over.

A 19-year-old man has been arrested and is being questioned at Swords Garda Station.

The car used in the incident has also been recovered.
