My brother was 16 when he came to live with my partner, myself and our children. He has always suffered with some type of intellectual disability and wasn't very smart compared to normal people. Whilst staying with us his life went down hill he ended up in prison and developed a pretty bad drug addiction which defiantly would of aided with his criminal history. Which was nearly 7 yrs ago now. Since then and serving his jail sentence he has cleaned himself up and his life is on track now. Sought of. I have recently learned that whilst staying with me my partners brother who is a junkie and was in his 40s at the time was constantly trying to feel my brother up several times. My brother tried to come out with it but nobody listened and it was kept quiet from me also. Back then he was quite distressed by it and he even attempted suicide at 1 stage. I have also learned aswell that my partners brother was feeding him up on his suboxone. I understand my brother was 16 and c lould of said no but he really is a slow learner and easily mislead. So my question is is there anything my brother could possibly do about this?
