Reporter Dave Bryan was conducting an interview around 10 p.m. when the suspect tackled him and his photographer, the station confirmed.
“All of the sudden, this guy came up from behind, he had a hood, and he knocked David on the head and he pushed the camera guy down. The camera guy went down, the camera went down, David went down,” witness Joseph Deguerre, said. “I was in shock.”
The suspect then fled the scene and the crew was treated for minor injuries, the station added.
The attack was under investigation by the Los Angeles Police Department.
“To attack a news reporter when he’s getting an interview? That’s just crazy,” Deguerre, 43, said.
Fourteen people were arrested during Monday night’s protest.
