SINGAPORE - A taxi driver was found dead in his taxi on Wednesday morning (Aug 1).

The police said they were alerted to a case of unnatural death at Block 675 Hougang Avenue 8 at 8.05am.

A 63-year-old Chinese man was found lying motionless and pronounced dead at the scene by Singapore Civil Defence Force paramedics.

The Straits Times understands that the taxi's door was open and the man's legs were outside of it while his body remained inside when he was found.

A Trans-Cab spokesman identified the driver as Mr Or Tiong Hee, and added that he has been with the company since July 9, 2011.

No passengers were on the taxi when the incident happened.

The spokesman added that the company found out about his death from his relief driver who was supposed to take over the taxi after Mr Or's shift.

"The relief driver had activated our towing crew to remove the taxi," said the spokesman.

The company had also been unable to get in touch with Mr Or's family as of Wednesday afternoon.

Police investigations are ongoing.
