A silver Audi sedan that spun out of control along Simei Avenue yesterday morning struck seven other vehicles, causing a 1 1/2-hour jam along the three-lane road .

Witnesses said the driver of the silver Audi was speeding and apparently in the midst of overtaking when his car collided with other vehicles and swerved to the road divider, leaving a trail of damage in its wake.

Mr Rajan Shirodkar, a vice-president of technology at OCBC Bank who was driving to work, said the silver Audi hit the rear wheel and side of his black Volkswagen Passat.

"My first reaction was to find out who the person was but, by the time I saw him, he was running away," said the 48-year-old.

Witnesses said the driver of the silver Audi - believed to be a young man dressed in a T-shirt and shorts - abandoned the car and fled the scene on foot.

Mr Chan K.C. was driving his wife to work when his car was struck from behind.

Said the 66-year-old, whose black Audi was damaged at the side and rear: "Our cars had all stopped due to heavy traffic when, suddenly, I heard a 'boom' sound. I am not too sure what happened but the vehicle hit me from the back."

The accident, which took place at about 9am next to the Institute of Technical Education College East campus, left Mr Chan's 65-year-old wife injured.

Mr Chan, a manager at a construction company, said his wife experienced pain in her stomach and back after the accident. She was warded at Changi General Hospital.

When The Straits Times arrived at the scene yesterday, police officers were present and the eight affected vehicles occupied two of the three lanes on the road.

Of the affected vehicles, the Silver Audi, Mr Chan's black Audi and Mr Rajan's black Volkswagen looked badly damaged.

Police said they had received a call at about 9.10am about an accident along Simei Avenue towards Tampines Avenue 2, and that investigations are ongoing.

The Singapore Civil Defence Force dispatched an ambulance to the scene after they were alerted to the accident at 8.55am.

Another hit-and-run accident had occurred late last month, when the driver of a white Honda also fled the scene after he caused a chain collision along Jurong Town Hall Road.

The car had rammed into the back of a motorcycle and sparked off a chain collision involving three other vehicles.

Investigations for the case are ongoing.
