A fire activated the sprinkler system at Pima Community College's Advanced Manufacturing Building on its Downtown Campus, Wednesday morning.
According to PCC, an individual lit a garbage can on fire outside of the building at 9 a.m.
The contents of the garbage can caught fire, which in turn caused the heat to break a window in the building, alerting the sprinkler system to activate.
No injuries were reported.
The investigation is ongoing.
