Withdrawal of criminal compliant

My tenant filed a false complaint against me.As a result of which FIR u/s 354A/506/509/34 was registered...Basic facts of the case is that I told her orally no of times to vacate the house but she refused to do so..At last, I sent a legal notice from my lawyer seeking eviction of the said house in terms of agreement by giving one month notice to the date of expiry of registered rent deed.On receipt of the said notice ,another day she filed a false complaint..Now with the help of common people she decided to withdraw the complaint...Till now chargesheet has not yet filed and I have not yet hired a lawyer.What is the right procedure to withdrawn the FiR at this stage. Police officer told me an affidavit is to be filed at police station by her stating the she is withdrawing the case,duly attested by notary on ?10 stamp paper or she can apply to court for withdrawl of complaint under section 257 CrPC.. So is this right..If yes ,then with which one I should proceed ?? Or Is there any other procedure.. Thank you...
