The Ridgefield Police Department has received a number of calls from people about what Police are calling “booing.” To “boo” someone, involves sneaking onto their doorstep during the night and leave tricks and treats.  While Ridgefield Police say this is often done in the spirit of Halloween, some residents have called 911 believing that someone was trying to break into their vehicle.  Residents have been vigilant for suspicious activity due to the increase of motor vehicle larcenies that Ridgefield and the surrounding area has been experiencing.
