() Los Angeles residents Scott Mitchell and Davanh DiMarco explained how they stopped an arson suspect escaping the scene at a popular Los Angeles park.

The couple joined “Banfield” to discuss how the July 13 incident unfolded and the erratic behavior of the suspect.

DiMarco was filming the scenery at Runyon Canyon as a means of encouraging her social media followers to go outside, but what she saw was more discouraging than her intentions.

“I saw this man coming out from the bushes, from behind this 50-foot palm tree, and … like seconds later, the whole palm tree was up in flames,” DiMarco told .

“I said, ‘Scotty, go get him, don’t let him leave.’ I made sure to capture his face, and I wanted to get a video of what he had done,” she added.

Mitchell, a former college football player at the University of Kentucky, chased down the suspect who was initially 150 yards away.

Once he was holding him for the authorities, Mitchell checked the suspect for weapons.

“I told him, ‘I’m Batman from Gotham City, and I don’t want to hear you talk,'” Scott said of his conversation with the suspect.

“I feel like it would keep him calm and make him feel like we’re in the same world, even though obviously we’re not. And he actually said, ‘Oh no, Gotham is gone.'”
