The Interstellar Criminal Police Commission or ICPC, colloquially referred as the Interstellar Police or the Galactic Space Police, is an investigative and law enforcement agency facilitating cooperation and coordination between planetary law enforcement agencies and for enforcing the law in interstellar space outside of planetary police jurisdictions. The Interstellar Police also has jurisdiction over cases involving terrorism and threats to national security and crimes that cross planetary jurisdictions, especially in areas of financial crimes, arms control, substance control, and cybercrime. The Interstellar Police has dedicated subdivisions for particular kinds of crime, and special agents tasked with investigation into these. It overlaps responsibility with the Central State Police in coordinating colonial and provincial police departments.
Prior to 3286, the Interstellar Police was subordinate to the National Police Department. However, the NPD was dissolved and its constituent agencies rolled into the Republic Security Department.
