The Putnam County Sheriff’s Office says several high-end vehicles have been stolen from driveways recently during the late night/early morning hours. Sheriff Robert Langley says the perpetrators, believed to be individuals from out of state, searched for vehicles that were unlocked, with the key left inside. Typically, the thefts were not discovered until several hours after the vehicles were driven away. The Putnam County Sheriff’s Office is currently investigating the thefts along with agencies from Westchester and Dutchess Counties.  Residents are being reminded to lock parked cars, remove valuables and have adequate driveway lighting.  People are being urged not to confront potential perpetrators as they should be considered armed and dangerous. Suspicious activity should be reported by calling 911 immediately.
