SINGAPORE - A 21-year-old navy personnel was killed in a car accident along Changi Coast Road on Friday (July 29) morning.

Five others in their 20s to 30s, who are from the Navy, were injured in the accident. They were admitted to Changi General Hospital, and two of them remained unconscious.

The Singapore Civil Defence Force (SCDF) said it was alerted to the accident, which occurred near the Changi Airbase and Changi Naval Base, at 6.35am.

Mr Yukio Matsuo, 21, who was killed in the accident, was the driver of the Subaru SUV which crashed into a tree, according to evening daily Lianhe Wanbao. He was trapped in the vehicle and had to be extricated using hydraulic rescue tools. He was pronounced dead at the scene by paramedics.

Mr Matsuo, whose father is Japanese and mother, a Singaporean, had apparently been driving his mother's car.

The family's domestic helper described Mr Matsuo as calm and someone who enjoyed spending time at home with his family, said the Lianhe Wanbao report.

According to Mr Matsuo's Facebook profile, he was a student of St Joseph's Institution and had studied marine and offshore technology at Ngee Ann Polytechnic. He started working at the Republic of Singapore Navy last year.

SCDF said it dispatched one fire engine, one red rhino, five ambulances and two support vehicles to the accident scene. Police investigations are ongoing.

A video of the accident was uploaded by Facebook user Noor Iskhandear, showing the scene as he was travelling on an SBS bus.

Multiple road traffic accidents have occurred along Changi Coast Road towards Nicoll Drive over the years, several of which have been fatal.
