The owner of a San Francisco tow truck company accused of trying to light his competitors’ trucks on fire has been indicated by a grand jury on charges of conspiracy to commit arson.

An owner of San Francisco towing companies who is already facing multiple indictments is facing an additional charge for allegedly plotting to burn the tow trucks of his competitors, prosecutors said.

Jose Vicente Badillo, the tow company operator already barred from doing business in San Francisco, allegedly plotted to set fire to trucks owned by his competitors.
