Texas firefighters who refused to be waved away by people outside a burning house extinguished the blaze, then found a marijuana operation inside.
San Leon Assistant Fire Chief Scott Lyons says a man with a water hose, standing in the driveway, was saying "Man, we got it. We got it."
Firefighters put a ladder to the second-story porch and went in anyway. Lyons says marijuana paraphernalia was everywhere. More than 100 plants were seized.
Deputies detained a suspect, who allegedly returned to try to destroy the drugs.
The cause of the electrical fire is sought.
San Leon is 30 miles southeast of Houston.
