MASON CITY, Iowa (AP) — Officials in northern Iowa are looking for a work release prisoner who walked away from a residential facility without permission.

Prison officials say 29-year-old Matthew Ernest Andersen left the Beje Clark Residential Facility in Mason City on Wednesday night and did not return.

Andersen was serving a sentence for domestic abuse assault and other counts in Cerro Gordo County. He was admitted to the work release facility on Feb. 27.
