SINGAPORE - A motorcyclist and a lorry driver have died after an accident involving a lorry and two motorcycles on Friday morning (Oct 11).

The Singapore Civil Defence Force (SCDF) said they were alerted to the accident at the junction of Woodlands Road and Mandai Estate at 7.55am.

A 53-year-old motorcyclist was pronounced dead by paramedics at the scene, the police said.

The 67-year-old lorry driver, who was unconscious when he was taken to Khoo Teck Puat Hospital, later also succumbed to his injuries, the police added.

The SCDF said the other motorcyclist refused further medical assistance and was not taken to hospital.

In photos circulating on social media, a body can be seen pinned under a Malaysian-registered lorry.

An eye witness to the accident, motorcyclist Zhang Jin Lun, told Chinese evening paper Shin Min Daily News that he did not see the lorry driver at the wheel before the accident happened.

The 45-year-old said that as he was making a turn, the lorry appeared to lose control and collided with the motorcycle ahead of him.

Shocked, Mr Zhang jumped from his bike and fell on a grass patch beside the road. The lorry struck his motorcycle after that.

Police are investigating the accident.
