Did Mr Fai Marwan "entrap" the men by posing as a 14-year-old girl online?

Lawyers The New Paper spoke to certainly think so.

But lawyer Chia Boon Teck said this does not mean the men involved can claim they were set up when called up by the authorities.

This is because Singapore's laws are not sympathetic to entrapment as a defence.

Mr Chia explained: "A crime is a crime regardless of the circumstances surrounding the commission of the crime. At most, the men could mention the entrapment as a mitigating factor."

Agreeing, criminal lawyer Josephus Tan said he was uncertain if the authorities would take action even if the case was reported.

Doing so, he added, "will only open the floodgates" and serve to encourage more "cyber vigilantes" to take action over perceived wrongdoings online.
