Two jail inmates have attempted an escape by ramming a stolen service van into an interior fence at the facility in Jackson County's Blackman Township.
The sheriff's office says Wednesday that the inmates then tried to ram perimeter fences about 2 p.m. Tuesday, but the crash with the first fence disabled the van.
Deputies subdued the inmates with stun guns and chemical spray. They could be charged with vehicle theft and attempted escape.
The sheriff's office says the van was on jail grounds when the driver was threatened by one of the inmates who took the vehicle's key.
The damaged fences have been repaired.
The jail is about 80 miles west of Detroit.
