A Hudson man was scheduled to appear in court for allegedly going through two Westborough restaurant drive-up windows naked. Rosildo Santos Jr. was expected to be arraigned Tuesday on a charge of open and gross lewdness. Police said they responded to a Dunkin’ Donuts just before 1 a.m. Sunday after workers reported a man at the drive-through window with just a coat over his waist. While an officer was talking to workers, Santos allegedly went past the window again, this time completely naked. Police said they found Santos trying to use the drive-up window at a nearby closed McDoanld’s. Police say that when he was pulled over, he was naked.
