The Riau Islands Police have revealed that a number of groups have been selling subsidized fuel to industries.
During an operation conducted from mid-August to early September, the police arrested 30 suspects and seized 64 cars, two boats and 106 tons of fuel.
"The cars that we impounded had been modified so they could each hold 100 litters of fuel," Riau Islands Police chief Brig. Gen. Arman Depary told media in Batam on Monday.
He alleged that several members of the Indonesian Military (TNI) were involved in the fuel smuggling case, and that the suspects had been handed over to the nearest military base.
On Tuesday, TNI Commander Gen. Moeldoko said that the alleged perpetrators were honour-based staff members.
