Brian J. White, an actor on the TV show 'Chicago Fire,' aids in the apprehension of an illegal immigrant using a blowtorch near a fire-prone area in Los Angeles.

A hero in Los Angeles saved his community from a suspected arsonist who tried to set fire to a neighborhood.

On Thursday, a man from Mexico was detained by several residents, including "Chicago Fire" actor Brian J. White, for allegedly waving a blowtorch on private property.

In Woodland Hills, White was readying to evacuate his neighborhood due to the Kenneth Fire, which had been fully contained, when he noticed something unusual outside.

"Suddenly, while packing up, I heard screaming outside our house, "Put it down, put it down," White recounted to Deadline. Assuming someone had a gun and my neighbor was in distress, my daughter hid in the closet and I ran upstairs to go outside and help my neighbor."

According to Planet Chronicle Digital, a man named Juan Manuel Sierra-Leyva, an illegal immigrant from Mexico, was screamed at by individuals in a video obtained by Planet Chronicle Digital.

White claims that a neighbor had pursued Sierra-Leyva to his own home, where he confronted him with a blowtorch. The neighbor was accused of attempting to set fire to flammable debris in White's trash can.

White, along with a third neighbor, stated that they "supported the man who was standing in front of our neighbor's house, inquiring why he was there, and the man became extremely hostile when asked about his presence in the neighborhood."

"He mentioned that he was searching for a spot to socialize. However, we responded, "This isn't the ideal location for hanging out.""

White and his neighbors initially planned to let the police handle the situation, but Sierra-Leyva's behavior became more aggressive, prompting them to make a citizen's arrest.

"Our neighbors work on cars in their garages, and we took them down, detained them, and waited for the police. Sixteen cruisers arrived within seven minutes of our call, and the rest is on the news."

Planet Chronicle Digital requested a comment from a representative for White, but no immediate response was received. According to Deadline, the LAPD arrested Sierra-Leyva for a felony probation violation, but there wasn't enough evidence to charge him with arson.

Throughout his extensive career, White has portrayed various characters in uniform, such as a detective in "The Shield," "We Belong Together," and "12 Rounds," and a police officer in "Ghost Whisperer" and the 2005 film "Dirty."

The training White received for hostage negotiation allowed him to remain calm during the difficult situation outside his home.

"Over the years, I've been on many police ride-alongs, and one of the key topics they discuss is staying calm and communicating. That's why I made it clear to the man that I didn't need an explanation. He was on my property with a lit blowtorch, so I was simply going to ensure that he waited for the police to arrive."

"We needed to determine if he had any weapons on him, and if we were in danger, he added. We tried to remain calm, but when it escalated physically, we took swift action by asking for assistance from neighboring houses with ropes and zip ties. I am grateful for the training I have received in police work, fire work, and fighting to be prepared for such situations."

On Wednesday morning, three fires were burning in Los Angeles County and one in Ventura County. Of these, the Palisades Fire had the least containment at 19%.
