SINGAPORE - Eleven passengers were injured after an accident involving an SBS Transit bus and a SMRT bus along Selegie Road on Friday (June 8).

Police said they were alerted to the accident at the junction of Selegie Road and MacKenzie Road at 9.50pm.

Two female passengers, aged 31 and 61, were conscious when taken to Tan Tock Seng Hospital (TTSH), said the police spokesman.

Another nine passengers suffered minor injuries, but declined to be sent to the hospital, said a spokesman for the Singapore Civil Defence Force.

According to photos and a video sent to citizen journalism site Stomp, the accident involved SMRT bus service 857 and SBS Transit bus service 64.

The Straits Times understands that at the time of the incident, the SBS Transit bus was stationary at the traffic light when it was hit at the rear.

Police investigations are ongoing.

In response to queries from ST, SBS Transit senior vice-president of corporate communications Tammy Tan said: "Our bus with 40 passengers onboard was stationary at the traffic light when it was hit by another bus."

"Four commuters were hurt and one was conveyed to the hospital, where she received outpatient treatment," added Ms Tan.

"Our priority is on their well-being and we have reached out to some of them already and are trying to get in touch with the rest to extend our assistance as best we can. We do wish them a speedy recovery."

Meanwhile, SMRT confirmed that one of its buses was involved in the accident.

"Our SMRT Care teams were immediately activated to reach out to those injured to render assistance," said Ms Margaret Teo, vice-president for corporate communications.

"We are concerned about the well-being of the injured passengers and we hope they recover quickly. We apologise to all affected bus passengers and for the inconvenience caused by the accident. "

Last month, on May 11, more than 30 people were injured after two buses from the same bus operator companies collided at a bus stop in Bukit Batok.

The accident involved SBS Transit bus service 157, which collided into an SMRT bus at the bus stop, according to SBS Transit senior vice-president of corporate communications Tammy Tan.
