On Sunday at approximately 4 a.m., law enforcement at the Houghton County Jail suspected a possible gas leak. Inmates were moved from the main cell block to a secure area.
A local heating professional was then called to the scene. No harmful concentrations of gas were detected, and the area was determined to be safe.
The Houghton County Sheriff's office was assisted by the Houghton Police Department, Hancock Police Department and Michigan Tech Public Safety.
