Police droids were used as the police at various spaceports such as the Stobar Spaceport on the planet Stobar and in the Cybloc system.
Several of these droids were contacted in 21 BBY after Dathomirian Zabrak Savage Opress choked the waitress Sassi in Plop Dribble's spaceport cantina. However, by the time the droids arrived, the Zabrak had already fled. They were also used as security at a space station in the Cybloc system.
