What can I do if my business partner has done fraud with me?

I know a person who offered me 43% stake in company as the company is in loss as stated , after we bagged numerous projects but the accused though send me e mail MOU numerous time but failed to signed the same giving excuses which conveyed him by e mail. Accused and his Company also accepted INR 19L from me stating loss, which is a serious lie after seeing his bank documents and ITR return. All the money paid by me . After getting the all the money from client around 3.9 Cr he only paid a part and latter filled a case against me U/s 500 IPC. Prior filling the case by accused I made a police complaint but they failed to register a FIR and latter I approached Hon'ble JMFC of my jurisdiction U/s 200 CrPC in which I eventually got Police enquiry U/s 202 CrPC. After going through details I come to know that the accused siphoned off the amounts for his personal. Police investigation will take long time to file report, so what can I do for that?
