Did the men commit a crime when they asked for sex from Mr Fai Marwan, who was posing as a 14-year-old girl?

Although sexual grooming is a crime, The New Paper spoke to five lawyers who said that the law also states that the offender must have communicated or met the minor on two or more previous occasions.

Veteran lawyer Chia Boon Teck said "there is no law" compelling Mr Fai to make a police report against those men, but he also believes the men cannot be charged for the acts "if they were merely discussed but not committed".

Criminal lawyer Amolat Singh agreed, adding that the men must also have "intentionally met or travelled with the intention of meeting".

The law is tough on predators who try to sexually groom children over social networks and is designed to catch anyone aged 21 or older who trawls the Internet with the intention of having sex with a minor.

The offence carries a maximum three-year jail term and a fine.
