SINGAPORE - A person was trapped in the driver's seat of a bus following an accident at Changi Airport on Wednesday (Sept 22).

The SBS Transit bus appeared to have crashed into a pillar of a Skytrain track which was running above it.

Three people, a 59-year-old male bus driver, and two passengers - a woman, 34, and a man, 42 - were conscious when they were taken to Changi General Hospital, said the authorities.

The accident occurred at about 1.05pm along 65 Airport Boulevard, between Terminal 3 and Terminal 1.

"A person was found trapped at the driver's seat of a bus. SCDF rescued the person using hydraulic rescue equipment," said the Singapore Civil Defence Force (SCDF).

It is unclear whether the bus driver was the one trapped in the driver's seat.

Confirming the accident, the Changi Airport Group said: "No services have been running on the affected Skytrain track and there was no impact to the infrastructure."

Police investigations are ongoing.
