A homeless man has been busted on suspicion of starting one of the wildfires ravaging Los Angeles — after brave locals tackled him as he wandered around using what looked like a “flamethrower.” The unidentified suspect was seen riding around Woodland Hills on a bicycle on Thursday afternoon setting fire to several old Christmas trees and garbage cans at the same time as the Kenneth Fire started, locals said. Renata Grinshpun told KTLA she was in her backyard when she heard a car screech to a stop and a man yelling, “Neighbors, he’s trying to start a fire! Call 911!’” One witness told Fox 11 that the suspect was “very focused on moving forward” with what the described as being more like a blowtorch. “He was like, ‘I can’t stop. I can’t stop. I’m not putting this down. I’m doing this,'” the witness said. “And we’re like, ‘We can’t be doing that right now.'” The LAPD confirmed an arson investigation was launched at Victory Trailhead, where the devastating Kenneth Fire broke out, with the area being treated as a crime scene. The Kenneth Fire sparked just after 2:30 p.m. and has since exploded to 960 acres and continues to rip through Ventura County with 0% containment as of Friday morning. Police responded to reports of a man attempting to light fires around 4:30 p.m. and “about 20 minutes, 30 minutes later a suspect was detained by citizens,” LAPD Senior Lead Officer Sean Dinse told KTLA. When asked whether the Kenneth Fire was a case of arson Dinse confirmed: “At this time, that’s what we believe. It’s being investigated as a crime.”
