SINGAPORE - A woman was killed after a private bus ran into her bicycle and several other vehicles at Pioneer Road North on Thursday (Jan 12) evening.

The Singapore Civil Defence Force (SCDF) said it was alerted to the accident at 6.03pm.

The cyclist, a woman in her 40s, was declared dead on the scene by paramedics, said police. The bus driver was arrested for causing death by a negligent act.

A man in his 60s was sent to Ng Teng Fong General Hospital, SCDF said.

It is understood that the bus went into a slip road, swerved right, then hit the cyclist before colliding with the other cars.

Footage from an in-car camera showed the bus mowing down a tree, cutting across a three-lane road and ramming into the fence on the divider.

It also narrowly missed a double-decker bus.

Nanyang Technological University (NTU) student Zolene Koh, 20, was on her way to the campus when she came across the scene of the crash.

The private bus was straddling the road divider. Other vehicles involved included a lorry and a white BMW, she said.

Traffic police were diverting traffic away from the accident site, and only public buses and shuttle buses from NTU could pass, she said.
