NORCO, Calif. (March 2) - More than 1 million rounds of ammunition, a cache of weapons and a tunnel were found at a man's home after an explosive fire that forced a neighborhood evacuation, authorities said Friday.

Crews worked to fortify the tunnel, which measured 5 feet wide by 8 feet long, to ensure it was safe. It appeared to be at least 10 feet deep and led into a back yard, authorities said.

The fire Thursday afternoon at the home in Norco, about 45 miles east of Los Angeles, caused some of the ammunition to explode.

The man tried to run back into the house after firefighters arrived and had to be restrained by sheriff's deputies, Riverside County sheriff's Deputy Juan Zamora said.

After the blaze was extinguished, crews discovered metal and wooden boxes of ammunition for shotguns, small handguns and assault rifles.
