Being tortured by wife and her relatives

Sir, I was married 3 yrs back. As my wife wanted me to go with her she offended me in many ways. Her relatives also offended me. After 2 years we got divorced. We had to pay 10 laks.This year feb 3rd my brother was married. The same is repeating. We have to take care of our parents. We don't want to separate as they are sick now. She is harming herself infront of us and complaining that my brother did it. Her parents and relatives came to our house almost 30 members. We were beaten badly. I was beaten on head and got 4 stitches. Actually they were trying to kill my brother. We locked him in a room.I went to nearby police station with wounds by walk. No vehicle stopped to help me. The police filed case but they just filed a small case. Does it come under attempt to murder. They wrote statement as I have given but they didn't write what I said. Still we can't sleep peacefully. Please give solution. We want to go by law. And our family want to commit suicide. We can't hear those abusive words of police and all other people. But we want to complain to all departments in India
