The 17-year-old boy from Torrington was charged Wednesday with second-degree assault and risk of injury to a minor in connection with an alleged January incident. Three other Torrington High School football team members were charged with similar crimes within the past two months.
The boy's name is being withheld because of his age, and his case is being handled in juvenile court. Details of his arrest are sealed from public view.
School officials say the boy arrested Wednesday has been suspended from school.
Officials are continuing to warn students that online bullying will not be tolerated and could lead to suspension or expulsion.
