"All three are being held at the Glendora city jail on $20,000 bail for wrecklessly starting a fire. They are being cooperative and I've been told by detectives that one has made an admission to our detectives and had admitted to setting this fire. Reportedly they were up, they had set a camp fire, they were tossing papers into the campfire and a breeze, reportedly, a breeze had kicked up and set this fire."
The three-alarm blaze prompted officials to call for an evacuation of the area and a created a general sense of panic. Fire officials say as many as 700 personnel are on the scene.
