Bail

Hii sir, My father is government servant i.e. patwari since 1992. The government has put work online suddenly 2016, though my father does not know anything about online system so he hired an operator for his work but he stolen my id and password and put government land falsely on 5-6 person and they had withdraw credit card on it and distributed among them, once my father came to know, he complaint to tehsildar and tehsildar complaint to police who filed case against my father on IPC 420,467,468,471,472 and 120B. The anticipatory has been rejected from the session court as well as high court and now my father is in jail. And then we apply for regular bail at session court but got rejected and now i want to ask whether we should apply for bail at high court or not because the police is not filing chargesheet to court until and unless they caught that operator but police is saying that they will show the diary to court and your father can get bail, really i need help, my father has done nothing and he is in jail.
