A BUS commuter was sentenced to three weeks' jail today for assaulting a bus driver.

Muhamad Fairus Abu Bakar, 32, pleaded guilty to punching the head of Mr Wong Hing Keong, 44, and kicking his body along Moulmein Road on June 6 last year.

A court heard that several passengers were boarding SBS 124 in front of Hotel 81 when Mr Wong told Fairus, who was smoking and chatting with a friend, to hurry.

After the two had boarded the bus, Mr Wong heard Fairus utter vulgarities.

When the victim asked Fairus what he had said, the accused stood up and kicked the driver's cabin door. A quarrel ensued.

Mr Wong stopped along Moulmein Road and the quarrel continued.

Fairus punched the victim on the head and kicked his body. He also pulled his uniform.

He could have been jailed for up to one year and/or fined up to $1,000.
