A fire early Wednesday at the Rockcastle County jail caused 13 inmates and two jail employees to be sent to hospitals.
Police and fire officials were called about 3:20 a.m. to the jail, which housed 102 inmates at the time, Kentucky State Trooper Lloyd Cochran said.
Four jail employees were in the building at the time. State police suspect arson, Cochran said. No arrests have been made.
Those taken to the hospital were suffering from smoke inhalation, but none of the injuries was thought to be life-threatening; many of those hospitalized have been released, Cochran said. The injured were taken to hospitals in Rockcastle and Laurel counties.
Never miss a local story.
The fire caused heavy smoke and water damage, Cochran said. The jail could be closed for several weeks.
All of the inmates were taken to the Laurel County Correctional Center, Cochran said. It was unclear whether the prisoners would be able to stay there until the Rockcastle County jail is repaired.
Jail employees told police that alarm and sprinkler systems worked as they are supposed to, Cochran said. State police will be able to confirm that during the investigation.
