In December Gothenburg police stopped a car they had spotted during a reconnaissance mission and inside found the drugs, worth an estimated 20 million kronor ($2.4 million).
The car appeared on the officers' radar in an industrial area of Hisingen, north-western Gothenburg, where they were tracking a foreign truck. Several moving boxes were transferred from the truck to the car, which quickly left the area.
Soon after police stopped the vehicle on the E45 road. The 40-year-old driver claims he was forced to carry the amphetamine, which was divided into one kilogram packages.
The truck driver is also suspected of committing crimes.
