An engineer was fined $5,000 on Thursday for punching and slamming a teenager's head against the steering wheel of a racing game machine.
Lau Teck Guan, 34, had admitted to causing hurt to the 15-year-old student at TKA Virtualand Arcade at Parco Bugis Junction at Victoria Street on May 26, 2011.
The court heard that at about 9pm that day, the victim's friend, then 16, was playing the racing game with Lau.
When his friend lost a game, the victim decided to take over the steering wheel. The victim then won subsequent games against Lau.
After winning the last game, Lau turned and stared at the victim and they got into an argument.
Lau got up from the game machine seat, and then punched the victim in the eye and cheek before slamming his head against a steering wheel of the machine.
Two of Lau's friends who were present then restrained him and told him to stop.
The victim called his parents and the police. By the time the parents and the police arrived, Lau had left the place.
When the victim spotted Lau at another arcade some months later, the victim again called the police. Lau was then hauled up for investigation.
The victim had swelling and bruising in his left eye and mild bruising on his cheek.
The maximum penalty for causing hurt is two years' jail and a $5,000 fine.
