VALLEJO (CBS SF) — A stolen car equipped with a tracking device led Solano County investigators to a Vallejo storage unit and the arrest of a man suspected of running a chop shop, sheriff’s office officials said Monday.

Auto theft investigators with the Solano County Sheriff’s Office said they served a warrant at a storage unit in the 100 block of Union Street in Vallejo on Oct. 14 based on a signal from a LoJack – a security system that allows law enforcement to track vehicles when they are stolen.
