King, who wasn't in the auto at the time, was seen after the attack, distraught.
The actress, who is set to appear in the new "Oceans 8" movie, was not in the vehicle at the time, but her friend was still in the driver's seat.
Unsurprisingly, Floyd has been arrested for felony child endangerment, misdemeanor battery, and two counts of felony vandalism.
News, James Knight Newman, the actress's son, was sitting in the parked auto in Beverly Hills when the suspected vandal jumped on the vehicle, shattering glass windows.
Per reports, witnesses saw Paul on a skateboard before he launched onto the hood of Jaime's Mercedes-Benz and wreaked havoc.
The release continued, "In an effort to protect the child, the female driver exited the vehicle and confronted the suspect at which time he threw a can at her, striking her arm".
The police received several calls of vehicle vandalism - including "kicking and jumping on the vehicles" - before they arrived on the spot within minutes and detained Floyd. When King's friend jumped out to confront the assailant, the man allegedly threw a can at her. He is now being held on $100,000 bail.
Floyd, of Los Angeles, fled the scene but was captured by police nearby. It's unclear when Jaime got out of the auto, but she was not injured.
Actress Jamie King found herself in a terrifying situation earlier this week. "The Department is conducting a secondary criminal investigation for California Penal Code Section 11414-Intentional harassment of a child or ward of another person because of that person's employment", the Beverly Hills Police Department said.
King could be seen hugging two unidentified women after the attack.
