A Garden City man was sentenced to 10 days in county jail and 36 months’ probation for a bomb threat that briefly closed a hospital.

The Finney County Attorney says 38-year-old Michael Clayton Mann was sentenced Thursday for aggravated criminal threat.

Prosecutors say housekeeping found the bomb threat in July 2012 carved into a men’s bathroom stall at St. Catherine Hospital in Garden City. Most of the hospital was closed while it was searched but no suspicious device was found.

The Garden City Telegram reports an investigation linked the threat to Mann, who worked in housekeeping at the hospital.

As part of the plea deal, three other charges were dismissed including one involving a second threat made to the hospital in October 2012.
