An overseas consultant called the police hotline multiple times alleging that a policeman had pulled a revolver on him - all because he felt he was not treated properly.

Yesterday, Satwant Singh was jailed for 20 weeks after he admitted to three of five charges of giving false information to a public servant on Oct 29 last year.

That day, Singh had a dispute with his neighbour and sought help from the police, said Deputy Public Prosecutor Eunice Lau.

Sergeant Muhammad Faris Suparli and his partner attended to the incident, but Singh felt that the matter was not handled well and called 999 at 7.04pm. He alleged that Sgt Faris had earlier put a revolver to his head and ordered him not call the police any more as he was drunk.

It was established that he had made the call because he wanted a more experienced officer to attend to his dispute with the neighbour.

About 40 minutes later, he called again and made a similar allegation, adding this time that he would be going after the police sergeant and if the police were to find him dead, it would not be "his problem".

DPP Lau said Singh had made the call because he was angry and again lied to a senior investigation officer that evening. Singh could not provide more details on how Sgt Faris had held the revolver, yet insisted he was not lying despite being told that it was an offence to provide false information to the police.

Seeking a sentence of three months per charge, DPP Lau said Singh had impeded public servants in carrying out their duties by making multiple calls that clogged up the hotline. She said there was unnecessary diversion of public resources; time was spent recording statements from the public servant involved; and the false allegation had caused distress to the officer.

Singh, who apologised for what he did, could have been jailed for up to one year and/or fined up to $5,000 per charge.
