Drunk neighbour nuisance

Our neighbour gets drunk often and starts shouting using unparliamentary language for hours standing on open place in front of his residing house which is just 1to 2 meters away from our bedroom and living room. He also increases his TV volume to Unbearable levels. Several times we requested him to turn down the tv volume and not to shout and use loud abusive language Which is causing disturbance to children in my house who are preparing for exams. It’s been happening for more than 6 months now. Neighbour who is causing this nuisance is not the land owner of that house but he is a labour who is residing there for free to protect that area appointed by land owner. Several times we complained to original land owner to solve the issue. Land owner kept warning him but not ready to evict the nuisance creator as he is not easy to lose his trustworthy protector of his land. My father is afraid of proceeding towards law and order to resolve the issue as the person who is creating issue belongs to a minority community and has the possibility of misusing his protection privileges against us as it’s the law which is one of the most misused laws already. I don’t know what to do to solve the issue without letting him misuse his protection powers. Please help. And yes, we have recorded now and then when he is drunk and creating nuisance.
