Dear Querist

file a RTI Application before Bank and got the information of withdrawal of the DD, if bank admit the fact that the person who apply for DD, withdraw the same against the cancellation of the same then the accused may file a discharge application before court

or

file an application to examination the banker under section 296(2) of Cr.P.C before framing the Charge, if the court think fit and proper then the court may allow the application u/s 296(2) of Cr.P.C and passed an order as per the examination of Banker, if banker admit the same as you mentioned then the court may pass discharge order in favour of the applicant/accused.

Thank you Nadeemji! 

Can I file discharge application immediately during the inquiry stage?

Dear Querist

yes, you may file the discharge application under section 245(2) of Cr.P.C

245. When accused shall be discharged.

(1) If, upon taking all the evidence referred to in section 244, the Magistrate considers, for reasons to be recorded, that no case against the accused has been made out which, if unrebutted, would warrant his conviction, the Magistrate shall discharge him.

(2) Nothing in this section shall be deemed to prevent a Magistrate from discharging the accused at any previous stage of the case if, for reasons to be recorded by such Magistrate, he considers the charge to be groundless.
