A teacher at Hill Regional Career High School was arrested Wednesday on 74 counts of sexual assault involving three female students.
Van Clifton McKenzie Adams, 41, of New Haven, turned himself in at the New Haven police department.
Police said Adams was arrested on three separate warrants charging him with the sexual assault of the students, who were all 16 or 17 years old.
Police began their investigation in November of 2001. The alleged incidents occurred between January and October of that year.
Police did not release additional information, and Adams, whose telephone number is unlisted, could not be reached for comment.
