A state prison inmate who failed to return to a minimum-security unit in Sioux Falls last week is back in custody.

Corrections officials say Inmate Phillip His Law was apprehended by the Sioux Falls Police Department Wednesday morning.

His Law had failed to return to Unit C, the minimum-security unit of the Jameson Annex to the South Dakota State Penitentiary, from his work release job search in Sioux Falls on March 21.
