A total of 11 Indonesian men aged between 23 and 45 were charged on Wednesday with one count each of criminal breach of trust after allegedly engaging in the illegal sale of 45 metric tons of marine fuel worth S$17,426 (US$13,000).

The 34-year-old captain, Robby Lirpa Sugiharto, and his 44-year-old subordinate Sapidi from Brightoil Petroleum (Singapore) allegedly misappropriated the fuel without their company’s knowledge, Shin Min Daily News reported.

At 3:15am on Monday, the Police Coast Guard arrested the pair after the stolen oil was found to have been sold to a foreign-registered tugboat operated by a crew of nine men off Bedok, in Singapore’s East Region. They were arrested as well and their vessel seized for investigation.

The 11 suspects were believed to have been involved in other similar cases as well, and they were not granted bail. They were remanded at the Central Police Division pending a court hearing scheduled for February 14.

If convicted, offenders could be jailed for up to 15 years and fined.
