Two teens hospitalised following violent road rage attack in Sydney's west

A manhunt is under way for a group of people who rammed a car off the road and attacked two teenagers in a road rage attack in Lakemba, leaving them both hospitalised.

An 18-year-old and a 16-year-old were driving a Honda hatchback down Yerrick Road in Lakemba at 10pm yesterday when they were rammed off the road and ordered out of the car before being violently assaulted by an unknown man.

Witnesses say the pair were kicked and punched repeatedly, with one having their head stomped on as they were on the ground.

"He started kicking him ... I was so scared when I saw him and the blood on his face," one witness said.

A 16-year-old was behind the wheel of the Honda.

His father spoke to 9News, saying he was unsure why his son was out late, as he is still learning to drive and doesn't have a licence, but that he did not deserve to be assaulted.

Anyone with information about the assault has been urged to contact Crime Stoppers on 1800 333 000.
