SINGAPORE (THE NEW PAPER) - Two men in their 20s were arrested for suspected drink driving in two unrelated accidents at the same scene along the Central Expressway (CTE) before the Yio Chu Kang Road exit on early Sunday morning (Jan 31).

The first accident involved two cars, while the second, involving a motorcycle, happened while police officers were attending to the first incident.

Both the driver of the car in the first accident and the motorcyclist were arrested for suspected drink driving.

The police said they were alerted to the first accident at about 1am.

Footage from a dash camera of a car on the left-most lane of the CTE shows a red car travelling at high speed in the next lane and slamming into a blue car from behind.

It is then seen spinning before crashing into the barrier on the side of the expressway.

The impact of the collision caused the blue car to turn turtle and debris to be strewn across all five lanes of the expressway.

The video had been posted on SG Road Vigilante's Facebook page by a Grab driver who was on his way to drop off his passengers.

The driver, who wanted to be known only as Mr Lam, 43, told The New Paper on Sunday: "I heard the sound of a roaring engine and knew that there was someone speeding. I slowed down to brace for an impact. But the driver in front of me was not able to slow down in time."

Mr Lam, who called the police to report the accident, said the driver of the speeding car was able to get out of the vehicle.

But the driver of the car that turned turtle looked to be in a bad condition, he added.

The Singapore Civil Defence Force (SCDF) said the driver of the car and his passenger were taken to Sengkang General Hospital. TNP understands that the driver was a 44-year-old male and the passenger was a woman. Both were conscious.

One other person refused to be taken to the hospital, SCDF added.

The police said a 27-year-old male car driver was arrested for suspected drink driving.

A second collision occurred while police officers were attending to the accident. Police said a motorcycle hit a police car belonging to the officers at about 1.30am.

The 29-year-old male motorcyclist was arrested for suspected drink driving. No injuries were reported for this accident.

The police are investigating both accidents.
