A fire set at a Tesla electric vehicle charging station in eastern Massachusetts was believed to have been set intentionally, according to investigators.

Police in Massachusetts say seven Tesla charging stations were intentionally set on fire and the incident is being investigated as suspicious."At this point it does appear that it was a set fire," said Littleton Fire Chief Steele McCurdy.

Upon arrival, firefighters saw seven chargers with heavy fire damage. After the Littleton Electric Light & Water Department cut power to the devices, they quickly extinguished the fire and notified the State Police Fire Investigation Unit assigned to the State Fire Marshal’s office.
