Highway police on the way back from a nearby checkpoint found the boy, whose name was withheld due to his age, in a Toyota Soluna sedan that was suspiciously parked in roadside bushes in Tambon Mae Lai at 6am.
Officers approached to ask him questions and to search his vehicle. They found two sacks containing 16 kilograms of heroin and the boy then reportedly admitted that he had collected the sacks from Chiang Rai’s Mae Sai district to deliver to a customer in central Thailand.
