The Norwegian Police Security Service (PST) is part of the Norwegian police service. Administratively, and in our preventive activity, PST reports directly to the Ministry of Justice. In criminal investigations and prosecution matters, we are under the authority of the Director General of Public Prosecutions and the Public Prosecutors' Offices.
We are responsible for preventing and investigating criminal activities linked with terrorism; with illegal intelligence gathering; with proliferation of weapons of mass destruction and of equipment, material or technology which can be used in the production or employment of such weapons; or with violent extremism. It also falls within our remit to counter threats towards Members of the Royal Family, Members of the Norwegian Parliament (the Storting), Cabinet Members, Members of the Supreme Court, and dignitaries representing similar foreign authorities.
Furthermore, our service has an advisory function with respect to other Norwegian authorities. Among the duties we carry out in this capacity is the issuing of threat assessments. Our threat assessments are delivered to the Ministry of Justice and other relevant bodies of authority, either merely to serve as written briefs, or also additionally to form bases for decisions. Their contents are classified in pursuance with the Security Act.
