SINGAPORE - Maserati driver Lee Cheng Yan, 33, who had earlier been charged with hitting a police officer with his car, was handed six additional charges in court on Friday (Dec 1).

Three of them are for offences under the Protection from Harassment Act.

The other three additional charges are for cheating, driving without insurance and a second count of driving while under disqualification.

Deputy Public Prosecutor Quek Jing Feng said that these were not the final set of charges and that investigations were still ongoing.

DPP Quek had earlier told the court that Lee was under investigation for offences including online gambling and unlicensed moneylending.

On May 22, Lee allegedly sent a man a text message, threatening to "splash" the latter's home if he did not "pay up". The amount involved was not stated in court documents.

He is accused of sending another message to the same man about two months later. This time, he purportedly told the man to "get ready" as his home would be splashed with paint and that it would "catch fire".

Lee is said to have sent a third message to another man on June 12. According to this message, this second man had blocked a certain phone number.

Lee then allegedly threatened to go to his home to "disturb" his family.

On July 6, Lee allegedly duped an employee of a car rental company into believing that he had a valid Class 3 driving licence. As a result, the employee is said to have rented him a car - which was not the Maserati - for 29 days.

On Aug 4, Lee purportedly drove the rented car in Shaw Road near Upper Paya Lebar Road while he was still under a ban that prohibited him from holding or obtaining a driving licence for nine months - from July 4 to April 3 next year.

He was still under disqualification when his Maserati allegedly hit Staff Sergeant Khairulanwar Abd Kahar in Bedok Reservoir Road at around 9.20pm on Nov 17.

In 2001, Lee was jailed for two months and banned from driving for 10 years for driving while under disqualification.

He was also charged on Friday with driving the rented car on Aug 4 without insurance.

Lee was first charged on Nov 18 with causing grievous hurt by performing a rash act.

The police said in a statement last month that Staff Sgt Khairulanwar, 26, stopped Lee's vehicle on Nov 17 while conducting enforcement checks. As he approached the car, Lee allegedly reversed and accelerated forward, hitting him.

The officer is said to have been left clinging to the driver's door and dragged for about 100m before falling onto the road. He suffered serious injuries, according to court documents, and was taken to Changi General Hospital.

Officers later arrested Lee in a Geylang Bahru Road HDB flat. The Maserati was found abandoned in Cedar Avenue, off Upper Aljunied Road.

Lee, who is represented by lawyers Tania Chin and Jeremy Pereira, was offered bail of $20,000. He will be back in court on Dec 28.

If convicted of causing grievous hurt by performing a rash act, he can be jailed for up to four years and fined up to $10,000.
