SINGAPORE – A man who helped his then employer acquire more than 28,000 tonnes of misappropriated marine gas oil worth around US$13.58 million (nearly S$18.36 million, according to court documents) was sentenced to seven years, four months and two weeks’ jail on Jan 10.

At the time of the offences, Wong Wai Meng, 58, was employed as a bunker clerk at Sentek Marine & Trading, a Singapore-based firm dealing with fuels.

Wong, who received more than $286,000 from the company for his assistance, pleaded guilty in November 2024 to 12 counts of intentionally helping the firm acquire the misappropriated fuel.

Several former employees who were key members of the group were dealt with in court earlier.

The group had secretly siphoned off more than 200,000 tonnes of gas oil worth more than $120 million between August 2014 and January 2018.

For the current case, the prosecution said that the rogue Shell employees had sold misappropriated gas oil to Sentek, which agreed to buy it at prices lower than the prevailing estimated market value.

The prosecution told the court that in 2013, Wong and Alvin Koh Koon Yian, 53, were assigned as bunker clerks to Sentek 22.

The prosecution added that another man, Ng Hock Teck, 61, who was then a man...
