Vancouver police say they are investigating 28 anti-Tesla incidents and will deploy more than 130 extra officers to "maintain order" at protests targeting the electric carmaker this weekend.

The force says in a statement that the incidents targeting Tesla are suspected to be politically motivated and all have occurred since Jan. 20.

It says 19 incidents were at dealerships and charging stations, including "hateful words and symbols spray-painted on buildings, eggs thrown at cars, and windshields smashed."

A further nine apparently political incidents targeted private vehicles, including rocks and liquid being thrown at cars, and windshield wipers being damaged.

Vancouver police say the incidents are believed to be motivated by Tesla CEO Elon Musk's involvement with the U.S. government.

Spokeswoman Const. Tania Visintin says while everyone has a right to lawful and peaceful expression, "nobody has the right to use violence, damage property, or intimidate others."

“There are a number of protests planned this weekend against Tesla, and we’re deploying a heavy police presence to make sure these protests remain lawful," Visintin said in the news release.

The VPD says there were no reports of incidents targeting Tesla dealerships or charging stations last year.

The force says investigations into the 28 incidents are ongoing, and police don't know how many suspects are responsible.

“We understand many people are distressed by world events and are looking for ways to vent their frustration, but damaging private property is not the answer,” said Visintin. “We encourage people to express themselves peacefully, lawfully, and with respect for others. Anyone who breaks the law will face arrest and charges.”

Police say the extra officers being deployed this weekend will include members of the its public safety unit.

Tesla dealerships across Canada have been hit by a series of protests and vandalism as demonstrators object to Musk's role in the U.S. administration of President Donald Trump.

Organizers of the recent Vancouver International Auto Show banned Tesla over safety fears for guests and exhibitors.
