A Waterbury high school teacher has been charged with sexual assault, accused of having a relationship with a student.
Jeffrey Lucian, 49, was arrested Thursday. He is charged with fourth-degree sexual assault.
Police confirmed Lucian was a teacher at Kennedy High School.
The investigation began when school district officials reported concerns. Investigators believe Lucian was having a relationship with a 16-year-old student and that it started sometime in the last few months. No other details were available.
NBC Connecticut has reached out to the school district for comment but has not yet heard back.
