Scott Sakajian was charged with willful cruelty to a child and battery on a person, according to the Los Angeles City Attorney's Office.
The video, which sparked outrage on social media, shows 10-year-old Alfredo Morales sitting on a bus bench with his older sister when Sakajian slaps him.
The boy reportedly damaged the Mercedes emblem on the front of his car. The boy's family lives in a broken SUV set up at a park in Arleta.
Sakajian's arraignment is scheduled for Friday, Aug. 2, at the San Fernando Valley courthouse.
