Quashing FIR / Refund of security deposit

My Dad has been accused in a fake FIR with IPC 147,148,427,379,C.W Sec 3(1) of Tamil Nadu Public Property Damages and Loss Act in crime no. 601 of 2011 of Vallioor Police Station, Tirunelveli District, Tamil Nadu. He has been granted bail by Madurai Bench of Madras High Court with CRL OP (MD) No. 14869 of 2011 with a condition of depositing a sum of Rs. 2,50,00/- to the Credit of crime no. 601 before judicial magistrate, Vallioor. It has been more than 5 years, the charge sheet remain not filed.When I tried to quash the FIR stating that the charge sheet has not been filed for a long time, the Police replied to Madurai High Court that the charge sheet has been filed.When I asked for the details in local court, I came to know that the charge sheet has not been filed. When I inquire about the details in CM special petition Cell, the police gave a reply that the charge sheet has been submitted to Public Prosecutor for his sign. When I ask the details through RTI, the police is threatening me not to try anything foolish against them. (1)What is the maximum duration for filing charge sheet for the above IPCs? (2) How should I try for quashing the FIR after this? (3) can I withdraw the amount deposited in court in case if we can't quash the FIR by some means, as we find difficult to make both ends meet, being an agriculture background? If I can withdraw the amount, will it be with interest for that amount deposited?
