DENVER (KDVR) — A Denver firefighter has been suspended for leaving a stuffed rat near another firefighter’s bunk, the Denver Fire Department said.

A Denver Public Safety disciplinary letter said firefighter Aaron McNally placed the rat as a threat toward another firefighter who testified in a discipline hearing against a friend of McNally’s who’d been demoted. The department says McNally intended to call the firefighter a “rat” for participating in the hearing.

McNally was suspended for 408 hours, the letter states.

The firefighter who received the rat ended up not testifying in the case out of fear of repercussions, according to the disciplinary letter.

McNally reportedly characterized the incident as “firehouse humor.”

The 408-hour suspension is the equivalent of 17 days since firefighters work 24-hour shifts.
