A teenager was trapped in a Redmart lorry after it collided with a car in Ang Mo Kio on Tuesday night.

The accident occurred at the junction of Ang Mo Kio Avenue 4 and Ang Mo Kio Street 11 at about 10pm, the police told The Straits Times yesterday.

The lorry fell on its side and the 18-year-old driver was trapped in it.

The accident drew a crowd which tried to help the driver, Lianhe Wanbao said in a report yesterday.

Warehouse assistant Zhong Xide, 40, told Wanbao that he was in a coffee shop nearby when he heard a loud "bang". When he turned to look, he saw the two vehicles had collided.

"I saw that the driver was stuck and could not get out, and together with a passer-by, we rushed over to ask if he was hurt," said Mr Zhong. "But the young man did not answer and looked like he was drifting in and out of consciousness."

He said the driver, who looked like he sprained his neck, responded after a few minutes.

A photograph published in Lianhe Wanbao showed a crowd of more than 50 people at the scene watching as officers from the Singapore Civil Defence Force (SCDF) rescued the man.

The SCDF told ST that its officers extricated the teen using hydraulic tools and took him to Tan Tock Seng Hospital.

The driver of the car, a 77-year-old man, was taken to the same hospital.

The police are investigating the case.
