NEWTOWN — A theater director accused of having sexual relationships with several underage girls was arrested on felony charges Thursday. The investigation began in November after a student told Newtown High School Resource Officer Liam Seabrook that Madden had contacted her through social media and engaged in an appropriate conversation, according to a news release. Police said they learned Madden had a pattern of contacting young women on social media and persuading them to meet with him in secret.
