How to recover money from relative when bank cheque won’t clear?

My younger brother has been falsely accused of rape under IPC Sections 376, 504, and 506. The woman (30+) was previously married three times and has not divorced her current husband (a court marriage). She has links to a known criminal. My brother (20) lived with her in Mumbai, but later left and married someone else. She then filed a rape case, showing a photo with sindoor and a tattoo of his name. Her statements to police and magistrate were inconsistent. She is demanding ₹15+ lakhs from us. (1) Can we get bail? (2) Can we apply to quash the FIR?
