My 11 year old stepson came yesterday telling us his 14 year old step brother from the other side has been holding him down stoking his legs and arms and using his fingers to try and poke his bum through his trousers. I'm absolutely furious as you can probably guess. He has said it happened previously and he spoke to his mum and step dad who told his step brother not to do it again. My stepson was crying so much last night he was sick. Am I right in saying this is still classed as sexual assault?
