Sweden says it has dismantled a money laundering network made up of groups that worked in the Russian language. An investigation turned up several cells suspected of washing dirty money inside the country. What stood out most was the scale, which investigators described as almost industrial. The networks involved a large number of people, with each taking on a piece of the laundering chain. Operating in Russian points to ties with criminal circles that cross Sweden's borders. The findings followed a probe into laundering offenses committed within Sweden. Authorities have not put a number on the sums involved, but the description suggests a major operation. The case places Sweden among the countries where laundering networks this size have managed to take root.
