Three men have been arrested after a taxi driver was badly beaten and his car hijacked.
The 32-year-old is being treated in hospital after the attack in the Tubber Lane area of Lucan, west Dublin, in the early hours of this morning.
Gardai said the man stopped to pick up a fare on the N4 at Palmerstown at approximately 3.40am, where he was threatened at knifepoint by three men.
He was forced to drive to the Tubber Lane area, where he was seriously assaulted and his car was stolen.
The driver fled and managed to raise the alarm. His car was found on fire a short time later.
A Garda spokesman said three men, aged 19, 21 and 28, were arrested shortly afterwards.
"The driver was conveyed to James Connolly Hospital with non life-threatening injuries," he said.
"The males are currently detained at Lucan and Ronastown Garda Station under Section 4 of the Criminal Justice Act 1984.
"The area of Tubber Lane has been sealed off for technical examination."
Investigators have appealed for witnesses in or around the Palmerstown Road area between 3am and 4am who saw any unusual or suspicious behaviour to come forward.
