SINGAPORE - A 77-year-old man was injured after the green Chevrolet he was driving flipped over on Sunday (Jan 17) morning.

The accident - which took place near the junction of Upper Serangoon Road and Bartley Road at around 9.36am - involved another car, a champagne-coloured Toyota.

The Straits Times understands that the man was the only person in his vehicle, although it is not clear how the accident occurred.

According to an eyewitness at the scene, several police motorcycles, police car and a towing truck were spotted occupying two left-most lanes of the thoroughfare after the accident, which caused some congestion.

Police investigations are ongoing, said a spokesman.

A Singapore Civil Defence Force (SCDF) spokesman said an ambulance, a fire engine and a red rhino were dispatched to the scene.

The man was in a "stable condition" and sent to Tan Tock Seng Hospital, SCDF added.
