Newtown Police are investigating the theft of a vehicle, which was recovered yesterday in Danbury.  Police say the Mercedes was stolen from the Danbury Mall area, and a Danbury officer spotted the vehicle leaving the parking garage.  Newtown Police asked that Danbury and  State Police follow the driver, but the pursuit was eventually called off due to heavy traffic.  The car was last seen on the highway, but it was equipped with electronic monitoring so officers were able to track it to Thorpe Street.  The vehicle was found abandoned, with minor damage.
