Son harassing old parents

I am writing on behalf of my parents, they live in Nallasopara (West) Dist Palghar. I live in Vasai (West ) Palghar.I am married My father is a retired central govt employee. My mother is a housewife. They stay with my brother(35) who is younger than me and my youngest sister (30). The house they stay is my parents house registered in the name of my mother. My brother is well educated but is addicted to alcohol and gambling...He has taken a lot of my father's hard earned money which he got on retirement under the pretext of starting small business which he never did. He is unemployed for last 3 years..earlier also when he was working he never gave his salary at home...he spent everything on alcohol and gambling. Since the time he is unemployed his drinking has increased a lot now recently he has become very violent. He abuses my parents and my little sister, last time he also hit my father. My parents registered a NC against him in July 2020 and then again last week as it has become unbearable...but the cops come they hit him and leave him again he comes home my parents dont allow him inside he kicks the doors and keeps abusing my parents from outside the house...... my parents medical and mental state is deteriorating because of this...both my parents have been admitted several times in hospital due to stress. All these years as a typical indian family my parents were not ready to throw him out of house...as he is the son of the family....but recently when they told him to the leave the house........my brother is such a disgusted person he's telling them you'll leave the house im not going anywhere, so now they have decided that they will find a house on rent and move there with my younger sister....and leave this house for him to stay.....my father is fears for his life as my brother is become very violent and he is scared my brother will hit him again when hes drunk. My younger sister is about the get married in 6 months....i do not like the fact that my parents have to leave their own house and stay on rent ...i know they are doing this for peace of mind ...but still....its their own house. They should be living there peacefully without any fear. I was checking google for a restraining order. Is there any way i can get a restraining order against my brother so that my parents can live in their house and he wont be allowed near them.
