Detectives, or investigators, were individuals who investigated criminal activity. Generally they were police officers, however, Jedi such as Tera Sinube who were able to use the Force to help piece together the crime, would assist regular police detectives with their investigations, in their capacity as a Jedi investigator. Detectives from the Coruscant Security Force would sometimes be referred to as inspectors. During the reign of the Galactic Empire, Imperial Security Bureau personnel could be assigned as investigators to investigate criminal and rebel activity. In the Imperial Security Bureau, there was also an elevated rank of Chief Investigator.
