Family giving life threatening warnings

Respected Sir/Ma'am We live in a single plot with 3 houses.The eldest is my father and his mother living with the younger one.We have fights with in the family where the other family members talk and abuse me and my brother, out of jealousy.They have bad intentions and talk all bad about us and interfere in our personal lives. My mother from the time she married had mental and physical tourtue.She was threatened when me and my brother was very young to be killed and on that my mother and her family had filed a case back then.My father and his family were warned about being sent to jail and later my mom continued to live with them as we were very small and needed our dad to support us in education and other needs.Now the problem is that a politician (Local Corporator)from our colony has interfered in the family matter and has given life threatening warnings to me ,my mother and brother.She says she will get us locked up and beat us up,she will send rowdies and spoil our career by getting us into drug case.My mom doesn't want to be in that house at all.This lousy female (Corporator) is forcing my mother to live with my father,do all the household work and fall on my grandmother's feet and beg for pardon.We refused to do all the nonsense that she wants to force on us.Our main concern is this corporator attacking on our lives.We as a family are not fearing to face her but need a little guidance to deal with this lady.I request for some input and information to deal with the situation.
