Crews attack Southern Calif. wildfire from the air

An arson suspect has been arrested in connection with a Los Angeles wildfire that forced evacuations in canyons where thick vegetation hasn’t burned in more than 60 years.   The cause of the fire in steep, inaccessible terrain near Topanga State Park had been deemed suspicious after officials discovered two ignition points about an hour apart.  

No buildings have been damaged and no injuries have been reported. But about 500 homes remain under threat. By Monday, the fire had charred a little over 2 square miles of brush and trees. Firefighting crews were continuing to battle hot spots in the wildfire zone along with water drops from helicopters and flame-retardant drops from fixed-wing aircraft on burn areas.
