Law enforcement and counter-terrorism agency of the Swedish government
The Swedish Security Service (Swedish: Säkerhetspolisen [ˈsɛ̂ːkɛrheːtspʊˌliːsɛn], abbreviated SÄPO [ˈsɛ̌ːpʊ] ; until 1989 Rikspolisstyrelsens säkerhetsavdelning, abbreviated RPS/Säk) is a Swedish government agency organized under the Ministry of Justice. It operates as a security agency responsible for counter-espionage, counter-terrorism, as well as the protection of dignitaries and the constitution. The Swedish Security Service is also tasked with investigating crimes against national security and terrorist crimes. Its main mission, however, is to prevent crimes, not to investigate them.
