Southbury Police are investigating another reported vehicle break in.  Police responded to the Southbury Dog Park on Roxbury Road shortly one night earlier this month on a report of a suspicious person in a minivan.  The officers saw the vehicle leave, and turned to follow, but the driver sped off.  Police later discovered that the window of a vehicle in the parking lot had been smashed.  The owner reported that a large tote bag and its contents were stolen.  Southbury police were investigating three other smash-and-grab incidents that occurred between August 24th and 30th, and said at the time that they may be connected.
