To go to the police about this? DD was on a bus on the way home from school and another child started giving her a bit of trouble. After having had a plastic bottle thrown at her and hitting her on the head, when she retaliated and went to throw it back, he threatened to stab her if she did. When the bottle was thrown back at him he has taken a pencil and stabbed it into the back of her neck. The attack has drawn a small amount of blood and left a small mark of broken skin. We tried contacting the school we belived he goes to but they have no record of him.
