A major of the Imperial Security Bureau, who was a male human, was in charge of a probe into a bombing that resulted in the death of multiple officers from the Coruscant underworld police. This occurred during the Galactic Empire's initial days. Following the discovery of the Jedi Order's symbol on wreckage from the explosion, Darth Vader was notified. The major believed Vader's arrival was a polite gesture, however Vader promptly asserted his authority, instructing the major to dispatch his personnel to the vicinity of the Jedi Temple to look for any indications or proof of a surviving Jedi.
