UPDATE: The Chattanooga Fire Department now says there was no fire at Moccasin Bend Mental Health Institute Wednesday.

"The fire investigator said a patient intentionally broke off a sprinkler head in his room, which also activated the fire alarm," a Chattanooga Fire Department spokesperson said.

The odor from the oily water from the sprinkler system had a scent similar to what someone might smell after a fire, the spokesperson added.

The patient's room was damaged by the water from the sprinkler system.

There were no injuries, but the fire investigator said the patient will be charged with making a false report and vandalism.
