THE HIV-positive chef who allegedly had oral sex with a teenager without telling him of the risk of catching the disease will also face cheating charges against him.

Chan Mun Chiong, 43, on Wednesday pleaded guilty to two offences - one under the Infectious Diseases Act and the other of committing an act of gross indecency.

His case was then transferred to a sentencing court, where his plea was to have been taken again.

But on Thursday, when he was due to plead guilty, the prosecution applied for the case to be adjourned, pending cheating charges.

Chan's summons charge accuses him of having had oral sex with the 16-year-old without telling him of the risk of being infected and without getting him to agree to accept that risk.

If convicted, he faces a fine of up to $10,000 and/or jail of up to two years.

The police charge is for having given and received oral sex from the teen in a toilet cubicle in Northpoint Shopping Centre in Yishun last Sept 15, an offence which carries a jail term of up to two years.

A pre-trial conference will be held in three weeks.
