(Blog Note: Please let us know what you think of this journalist’s focus on water damage rather than the lives and property saved by the sprinkler system in this overnight, high-rise fire).   Orange police and fire officials responded around 12:15 a.m. to reports of a structure fire at the Community Garden Towers in the 4000 block of West Garden Grove Boulevard, and found smoke coming from the fourth floor, officials said.

Authorities found a mattress on fire on the floor and the flames activated the sprinkler system in the building. Authorities said the building was evacuated and electricity may have been briefly turned off, but residents were able to re-enter the building shortly after the fire was extinguished.

Orange police initially detained a man who lives in the unit where the fire started on suspicion that he may have intentionally started it, Deputy Fire Marshal Casey Fieldhouse said.

But he was later released and not arrested, police Sgt. Phil McMullin.  Three people were displaced due to the damage and were assisted by local Red Cross officials. Authorities did not initially release the cause of the fire or damage estimates.
