California police are searching for two suspects after separate incidents involving Tesla vehicles being vandalized marked the latest acts of violence against the brand across the country.

Police in Novato are on the search for a suspect who vandalized a Tesla Cybertruck parked in a driveway early Saturday morning. Around 4:20 a.m., officers said the suspect appeared to case the home before returning with a concrete rock about an hour later.

The Tesla Takedown movement Saturday attempted to surround all 277 of the automaker’s showrooms and service centers in the U.S. in hopes of hitting Musk's bottom line.

Shares of Tesla entered Monday down more than 34% year to date, and the stock has been cut nearly in half from its peak in December.
