Jacob Makwana, 26, was arrested and booked Wednesday morning, authorities said. The Los Angeles County District Attorney's Office charged him with assault with a deadly weapon, felony vandalism, and throwing an object at a moving vehicle with intent to cause great bodily injury.
The case stems from an Aug. 9 incident that was recorded on video by political activist Amos Young, who was behind the wheel of his vehicle when he encountered a man who was allegedly dumping illegally.
The footage shows the encounter turning violent when the suspect picks up a rock and throws it at the car.
"I was looking to help and then I was attacked violently," Young said. "Beating, punching, stomping, tearing up my license plate, trying to get inside my car and bust open my windows."
