The Tahv Constabulary functioned as the police force within the Lost Tribe of Sith's capital city of Tahv, situated on the planet of Kesh. During the period of the Hilts Restoration, their commanding officer was the Prefect of Police, princess Takara Hilts.
In the year 2974 BBY, personnel from the Tahv Constabulary, under the direction of Prefect Takara Hilts, successfully captured Parlan Spinner. Spinner, an outlaw and anarchist, had previously tried to murder Grand Lord Varner Hilts amidst festivities marking the Lost Tribe's initial arrival on Kesh during the Great Hyperspace War.
