SINGAPORE - A motorist in a road rage row twice rammed his car into a rival's vehicle, after asking him: "You wanna play punk with me now?"

Chan Swee Liang intentionally shunted his rented black Mazda into the back of Mr Ahmad Ismail's stationary silver Nissan, throwing him onto his steering wheel and injuring him, before driving after him as he fled on foot.

The 42-year-old was sentenced to more than a year in jail on Thursday (May 24) after pleading guilty to six charges, including committing a rash act that causes grievous hurt.

The court heard that at 1.25am on Sept 8, 2016, Chan approached Mr Ahmad and asked him to move his car, which was parked near the exit of an open-air carpark on Ubi Avenue 1.

A row erupted, with Chan asking Mr Ahmad if he wanted to "play punk", before both men got into their cars.

Chan drove off but returned a few minutes later and rammed the back of Mr Ahmad's stationary car, knowing he was inside. He reversed and rammed it a second time, throwing Mr Ahmad off balance as he got out of his vehicle.

Mr Ahmad saw Chan reversing again and stood in front of him, but Chan accelerated then chased Mr Ahmad as he ran off.

The chase ended when Mr Ahmad ran on the pavement. Chan sped off and abandoned his car at its rental company.

Besides Mr Ahmad, there were two other witnesses to the incident.

Mr Ahmad called the police and sought medical attention for a minor spinal fracture and tenderness in his neck. He had not been wearing a seatbelt when his was shunted.

Chan was jailed 10 months for a rash act which causes grievous hurt, another eight weeks for causing a rash act that endangers human life and another three weeks for not rendering assistance to the other party.

He was also disqualified from driving all classes of vehicles for five years.

Anyone found guilty of committing a rash act causing grievous hurt can be jailed for up to four years, fined up to $10,000, or both.

For failure to report the accident to the police or furnish Mr Ahmad with his particulars, he faced a jail term of up to three months, a fine of up to $1,000, or both.
