SINGAPORE - A man was sent to hospital unconscious after being knocked down by a bus at Depot Road on Monday evening.

The Singapore Civil Defence Force (SCDF) said that they were alerted to the accident at around 7.10pm.

An ambulance was sent to the junction of Depot Road and Depot Close where the accident occurred.

The 25-year-old man was taken to the National University Hospital in an unconscious state, SCDF said. The hospital was alerted to be on standby to receive the patient.

A short video of what happened after the accident was uploaded online to Facebook group Singapore Road Accident Alerts on Tuesday morning.

In it, the bus was seen parked in the centre of the road. About a dozen onlookers had gathered on the grass by the side of the road. Cars could be seen behind the bus.

The bus driver appeared anxious as he paced and gestured, then ran back into the bus.

When contacted by The Straits Times, a spokesman for SBS Transit said that the victim had "dashed out onto the road".

"This matter is currently under police investigation but based on CCTV footage that has been retrieved, it is apparent that a man suddenly dashed out onto the road just as our Service 57 bus was passing," said Ms Tammy Tan, senior vice-president of corporate communications at SBS Transit.

Shin Min Daily News reported that the victim was seriously injured but is in a stable condition.

Police investigations are ongoing.
