My old parents getting harassed by my Uncle.

Hi, My parents are being harassed by my father's younger brother and his cousin brother since his mother's death. The details are as follows: My Uncle asked my widowed grandmother to stay with him to take care of his young daughter. He agreed to look after her and take care of all her expenses in life and death. But after his daughter grew up, he started harassing her and forced her to move to our house. Later because of her age, we agreed to keep her for half the year. But this was often breached by him. My father suffers from Paralysis and my mother is sick. Also my brother is handicapped. They still looked after our granny who was 93 yrs old. But later the strain was too much. They could not keep up physically and forced the Uncle to take her back. She died shortly after at his house under dubious circumstances. We did not want any acrimony so we did not press charges. But afterwards, My Uncle has been harassing us all the time. He got a mango tree laden with fruits cut and took the produce away. He had taken the permission from the forest dept and the police did not entertain us. He also complained to the Village grampanchayat about non repayment of Rs. 18000/- due for granny's dashakriya ritual. We have a common septic tank , for which we have paid money. But he wants to cut the connection. Also he keeps on concocting stories about fake land deals and loans. My father gets a small pension and the family lives on that. They do not have physical or emotional strength to put up with this harassment. The Police refuse to file any complain saying that they have not beaten you guys. Pls help!!
