BILLINGS, Mont. (AP) — Authorities are searching for three inmates who escaped from a jail in southern Montana.

The Billings Gazette reports residents were being told Saturday to make sure their doors are locked and their keys are not in their cars after the men escaped from the Big Horn County jail on Friday night. Sheriff’s officials say the men, identified as 25-year-old Andrew Parham, 34-year-old Anthony Castro and 34-year-old Stephen Caplett, are not armed but are considered dangerous.

No one was injured during the jail break.

Sheriff Mike Linder declined to give details about the escape but said the inmates caused some property damage. The men were last seen wearing grey and white striped uniforms.
