SINGAPORE - Wanting to earn fast cash, a full-time national serviceman, who also owned a repair company, allowed con artists to deposit more than $440,000 of their ill-gotten gains into his firm's bank account in 2016.

Nicholas Ryan Khoo was promised a 5 per cent commission based on the amounts he received, the court heard.

Khoo, 23, who served with the Singapore Civil Defence Force, was jailed for 15 months and fined $3,000 on Tuesday (June 12) after pleading guilty to two counts of receiving stolen property and one count of being involved in illegal gambling activities.

Khoo's two accomplices, his former platoon mate Rausyan Sajjad Mohamad Rafie, 24, and Rausyan's sister, Shaqilah Mohamad Rafie, 25, had been dealt with earlier.

They were each jailed for 16 months in January after admitting to two charges each of abetment by conspiracy with Khoo to receive a total of $441,545 in a bank account belonging to his firm known as Khoo Repairs.

On Tuesday, District Judge Marvin Bay said that Shaqilah had been living in Kuala Lumpur with her Nigerian boyfriend David Adewale Oladokun, who was part of a syndicate based in the Malaysian capital.

Mr Adewale had told his girlfriend that his syndicate committed offences including extortion as well as love and wire scams.

Judge Bay added: "Mr Adewale told Ms Shaqilah that the syndicate needed a bank account to receive money derived from scams and tried to persuade Ms Shaqilah to set up a Singapore company bank account to receive the money."

When Shaqilah returned to Singapore in 2015, she told Rausyan about her Nigerian boyfriend and the syndicate. She asked if he had any friends with company bank accounts who were interested in earning commissions by helping the criminals. Rausyan approached Khoo, who agreed to be part of the plan.

While Khoo was promised a 5 per cent commission, the siblings were told that they would each earn 2.5 per cent.

On March 4, 2016, $234,770 was transferred into Khoo Repairs' bank account and it received another $206,775 four days later.

Khoo received $11,200 for the first wire transfer. His two accomplices also took their cut.

The trio did not receive any commission for the second transfer as Khoo's bank later blocked their attempts to withdraw cash.

The offences came to light on March 12 that year when Singapore's Commercial Affairs Department received a complaint from a company known as Faith Universal Investments.

The Barbados-based firm stated that it had been duped by spoofed e-mails into wiring a total of $441,545 from its bank account into one belonging to Khoo Repairs.

Khoo has also admitted to acting as a dealer in an illegal game of Texas poker in a unit at Odeon Katong in East Coast Road on Dec 22, 2016.

Court documents did not state if Mr Adewale is still at large or if he has been dealt with in court.
