Police Departments across the Greater Danbury area are once again reminding residents to lock car doors at night and not to leave valuable items inside vehicles.  Keys should also not be left inside unattended cars. While everyone should abide by this advice, Monroe Police say residents who live off Route 110 and Barn Hill Road should pay special attention as these areas of town continue to see the highest number of entered and stolen cars.  Police continue to patrol all areas of town and have made arrests in many of these cases.
