[UPDATE April 24]

The 42-year-old male driver of the black car, who was assisting with investigations, was discharged from the hospital on Wednesday (April 24) and was subsequently placed under arrest for dangerous driving causing death, the police said in response to media queries.

The man's driving licence has also been suspended with immediate effect.

Two people died following an accident involving six vehicles at a traffic junction in Tampines on Monday (April 22) morning.

They include a 17-year-old female car passenger and a 57-year-old female van passenger, who were taken unconscious to hospital where they later died, the police told AsiaOne.

Six other people were conveyed conscious to hospital — three male car drivers aged between 42 and 48, a 64-year-old male van driver, a 11-year-old male car passenger and a 11-year-old male minibus passenger.

Additionally, a 42-year-old female car driver and 39-year-old male van passenger later sought medical attention on their own.

The 42-year-old driver of the black car is assisting with police investigations.

On Monday morning, dashcam footage posted on Facebook group Singapore Road Vigilante showed a black car speeding along Tampines Avenue 1 while switching lanes.

A 45-year-old salesman surnamed Li was driving his daughter to school when he saw the car driving erratically.

Speaking to Shin Min, he said that the speeding vehicle switched from the left lane to the right to overtake the white car in front of it.

Without signalling, the black car suddenly switched back to the left lane, colliding with the white car and causing it to swerve.

While the driver of the white car managed to regain control of the wheel, the black car sped away.

It allegedly ran a red light and caused another accident at the traffic junction several metres away.

A video of the aftermath, which was posted to Instagram page Sgfollowsall, showed six vehicles involved in the collision.

According to Shin Min, one of the affected vehicles was a school bus and a male student had been injured in the accident.

Responding to AsiaOne's queries, the Singapore Civil Defence Force (SCDF) said that it was alerted to a road traffic accident involving a few vehicles at the junction of Tampines Avenue 1 and Tampines Avenue 4 at about 7.07am.

Upon arrival, SCDF personnel saw a person lying on the road with one leg trapped under the wheel of a car.

They then used hydraulic rescue equipment to free the person's leg.

"A few members of the public, including a nurse and two off-duty SCDF officers, had rendered assistance to the injured persons following the accident," the SCDF said.

"The SCDF will be reaching out to commend them for their public spiritedness."

Out of the eight people taken to hospital, four were sent to Changi General Hospital, two to Tan Tock Seng Hospital, and two to KK Women's and Children's Hospital.
