Police say it’s unclear if there is a connection between vandalism of Tesla cars in Brookline and arson fires at Tesla charging stations in Littleton amid the sharp criticism of Tesla CEO Elon Musk for slashing the federal workforce.

Several Tesla vehicles were defaced Sunday afternoon in Brookline Village and West Roxbury when a suspect placed stickers critical of Elon Musk onto the cars. Boston police are investigating the West Roxbury incidents. Brookline police confirmed they’re also investigating the vandalism in their town. Vandalism against Tesla vehicles and properties have spiked in the early days of the Trump administration, in the U.S. and globally.

Dan Saltzman of Brookline has owned a Tesla since 2019.

He said his Tesla was parked across the street from his Brookline home when it was defaced with a sticker, and he is angry about the damage to his vehicle.

“I just noticed a big sticker of Elon Musk looking like a Nazi stuck to my car. And, you know, not the type of sticker that you can remove at least not easily,” Saltzman said.

Brookline police said one of the victims confronted a man on bicycle and recorded it, and police posted the video on social media and asked the public for help in identifying him.

As a result, police were able to identify the man suspected of vandalizing the Tesla cars earlier this week and he will face felony charges of defacing property. Late Wednesday, Police arrested 39-year old Harrison Grant of Roslindale, as the suspect that was seen riding an electric bicycle, with a basket and a Palestine flag on the back. He is charged with six counts of defacing property .

Saltzman said most Tesla owners in Brookline have them for environmental reasons, not because they like Musk.

“Because people in Brookline are conscious of the environment, conscious of the car choices they make with respect to the environment. And nobody in Brookline bought a Tesla because they like Elon Musk. They bought a Tesla because it’s an electric car,” Saltzman said.

In Littleton, firefighters responded to reports of a fire at The Point Shopping Center on Constitution Avenue at 1:10 a.m. Monday morning. More than half a dozen Tesla charging stations were set on fire in an incident that has been labeled arson by fire officials.

“Whether or not it is politically motivated, we have no idea at this point, but it was a heinous accident that destroyed property,” said Littleton Police Chief Matthew Pinard.

There were no injuries reported, and Pinard said they are reviewing surveillance footage and following every lead.

Massachusetts has a handful of Tesla dealerships including Boston, Natick, and Dedham and all of them referred calls about the car’s safety mode to their main headquarters in Austin, Texas.

Tesla vehicles have a “sentry mode” which when activated has a built-in camera and proximity sensors that detect and help prevent theft, break-ins and vandalism and other criminal activity.

Saltzman said he did not have his sentry mode turn on, because it’s expensive and uses a large amount of electricity and contributes to emissions. But from now on he’ll will use it 24/7, so he’ll have evidence of any criminal activity.

“The idea that somebody thinks vandalizing Tesla’s and making 5 million Tesla owners fear for their car to prove a political point when what they’re actually doing is the opposite of what their politics are is counterproductive.”
