RAPID CITY, S,D, (AP) — Authorities are searching for an inmate who escaped from a minimum-security prison in Rapid City.

Prison officials say Clarence Ferris, 30, left the Rapid City Community Work Center without authorization Sept. 12. He is serving sentences for possession of a controlled substance and unauthorized ingestion of a controlled substance. All of the convictions are from Pennington County.

Authorities say walking away from a non-secure correctional facility without authorization could warrant a charge of second-degree escape, punishable by up to five years in prison.
