Father (62) abused with foul language by SON and Myself (34) by BROTHER

I am writing on behalf of my father. He is 62 years old, currently dependent on me since 6 years, no pension. Last few years he has been mentally abused by my brother and dad is currently staying with me. He has a small property at his hometown which is in Moms (Late) name. We are 3 [Myself 34-single/ sister 30-married and stays with husband(i supported dad for the wedding expense)/ brother 28-recently got married in Apr'21(expense is done by me alone)] My brother was staying on rental basis in front of our flat for 3 months. He didn't pay any rent for 3months and he ran away without even informing us and the owner. he was using dad's scooty and and he was paying the EMI infact. Now he has stopped paying EMI for scooty and now the Lender is continously following with dad as the loan and two wheeler is in dad's name but he uses the two wheeler. Now we couldn't find him where he is and he has blocked all our numbers. He had informed lender that he doesn't have the scooty with him. He also took some money around 20K from my place when he was staying at my home. Am taking care of my dad now.. After sister got married, he is not supporting family.. He got addicted to drinks. Only thing he does is drinks and fights at home. I was stuck in between and couldn't even look after my life. 1. Dad and myself are not feeling safe to stay at our place and even to go out ? What can be done on this ? 2. How can we get this Scooty and EMI thing closed ? 3. Dad doesn't have monitory support to bear the legal expenses, is there any agency/NGO in Vasai-Virar, Maharashtra who can help and guide him ? 4. What about me who supported the entire family for these many years and left with nothing ?
