‘Operation Adam’ has primarily targeted suspects involved in the smuggling and sale of narcotics.
In addition to millions of kronor and several firearms, police have also seized 6kg of heroin, 30kg of amphetamines and 12kg of cocaine over the course of the operation, which was launched in April 2008.
Four people have been expelled from Sweden and the national courts have already convicted a number of the people involved on drugs and weapons offences.
The operation, referred to internally as Adam, is being led by the Västra Götaland county police force in cooperation with Serbian, German and Dutch authorities, as well as Europol, Interpol, Nordic coordination officers and other regional Swedish police forces.
