What should I do after cheque bounce and fraud case?

I sent around 15 lakhs to my friend's business account for business purposes by taking a loan in my name. He paid the EMI for a year. After my marriage, he started covering some expenses and I gave him money for the wedding. Later, he stopped paying the EMI and claimed he spent the 15 lakhs on my wedding. He stopped responding and may have tried to cheat me. I filed a police complaint, and he gave me two cheques for 5 lakhs each. Both cheques bounced, and now he has complained to the SP about being threatened by the police.
