Preston — State police are investigating multiple cases of vandalism in North Stonington and Preston, including Maple Lane Farms in Preston.

Owner Allyn Brown said Wednesday afternoon that the side of his office and one of his signs were spray-painted Saturday night, and a pick-your-own shed and a tractor-trailer on his property were tagged Monday night. Designs included swastikas and other Nazi emblems.

“It’s not nice stuff,” he said.

Brown said other houses in the area also were tagged.
