The homeless arsonist who was apprehended close to a wildfire in Los Angeles was revealed to be an undocumented immigrant.

According to RadarOnline.com, a video of Mexican national Juan Manuel Sierra-Leyva walking with a yellow blowtorch before being beaten by irate residents in Calabasas, California, has led to his being listed as a potential suspect in starting the destructive fires.

Sierra-Leyva was purportedly seen riding a bicycle in Woodland Hills on Thursday while toting a sizable “propane tank or a flamethrower.”

Since then, he has been charged with igniting a fire behind a car before nearby residents stepped in and put out the flames.

“I can not stop,” the suspect said, according to one witness who spoke to FOX 11. “I can’t stop. I’m not putting this down. I’m doing this.”
