The rash of thefts from cars and stolen motor vehicles isn't just a problem for Connecticut towns in the Greater Danbury area. New York State Police are investigating cases in Putnam County and elsewhere in the lower Hudson Valley. Since March 1st, over 400 stolen vehicle cases have been opened in Westchester, Putnam, Dutchess, and Rockland Counties. Numerous arrests have been made by multiple agencies. Many of the vehicles have been recovered, but Troopers say they often suffered severe damage from the perpetrators. New York State Police Troopers are asking that residents lock unoccupied vehicles and remove all keys, key fobs and personal items from inside the car. Keys or key fobs left inside the vehicle is the most common factor shared amongst these cases. Trooper say many of the vehicles stolen have been from affluent neighborhoods.
