Police arrested a Norwegian and a Lithuanian man at a warehouse at Kjørbekk in Skien on Saturday 21 November 2020.[1] Between 700 and 800 kilograms of hashish were found in a Polish-registered tractor with a trailer, which the Southeast Police District called one of the largest single hashish seizures in Norway.[1] Police put the probable turnover value at about 140 million kroner and said the drugs were likely intended for much of the country.[1]

A third Norwegian man was arrested afterwards, and police said all the men faced serious drug crime allegations, with more arrests possible.[1] One police hypothesis was that the hashish had arrived with the Polish trailer.[1]
