A report of a gas leak prompted the evacuation of the Schuyler County Courthouse in Lancaster Wednesday.
It happened at 11:20 a.m.
All county offices were evacuated as well as the Schuyler County Sheriff's Office.
The three inmates housed in the jail were transported to the Adair County Jail.
In all, around two dozen people were evacuated from the courthouse while officials tried to determine if there was a gas leak, and if so, where it was.
Schuyler County Chief Deputy Luis Perez told KTVO the all-clear was given at 12:40 p.m. Wednesday.
No gas leak was found during the evacuation.
The three Schuyler County inmates have since been returned to the jail in the basement of the courthouse.
