About 2 hours ago 14 year old DD came home in tears, she was walking home, got to the traffic lights up the road from our house. There's a pedestrian crossing there however there was only one car there which had stopped so she crossed anyway. A man came out of the car and started shouting at her for not using the crossing properly, he grabbed her arm so she tried to get away and he tightened his grip. A lady also crossing the road stopped him and guided her away from him, she walked her home since she was going in the same direction and helped DD explain to me what happened. I realise DD probably should have pressed the button and waited, she said the lights were green so i assume the man hadn't noticed, but it still doesn't give him the right to grab her arm. Is it worth getting the police involved?
