Wrong fir filed and victim made the culprit

My mother(aged 50) was slapped and beaten up by a man in our society. When she went to the police station to file a FIR, he was slapped with IPC 323, 504. As he was informed that he has a FIR against him he urged the police to file a FIR against my younger brother (aged 22) for outraging modesty of his daughter since 2 months. And consequently my brother was framed in the false case and sections IPC 34, 509 were imposed on him. Since the police inquired and found that my brother's background was clean they granted him bail through the court. On next day of this incident my mother did go to the police station to file a proper FIR against him but the police refused saying that the opposite party has filed an FIR against you and we cannot lodge your case. Seeing there was no action against my mother or brother, the culprit went to the police again and pestered them to file more sections against my entire family for outraging the modesty of his daughter. And my father, my mother, me and my younger brother were slapped with IPC 354, 534, 509. We are reputed family of 4. My father and mother are government servants, I work as a Program Manager with The Times of India and my younger brother is pursuing graduation. I need help to get out of all this as this fabricated case is taking a toll on our lives drastically.
