Tesla Italy said that it is cooperating with police, and that it had turned over surveillance video from the vehicles themselves.

Italian police are investigating a possible arson attack after more than a dozen Tesla cars were burned at a dealership at the edge of the capital early on Monday morning. A total of 17 cars were damaged in the fire after a blaze was reported around 4:30 am, Italian news agency Ansa reported. No injuries were reported.

Tesla has been increasingly under attack since Elon Musk endorsed Donald Trump and became his senior adviser for the Department of Government Efficiency.
