What to do if some false FIR lodged against me

We got seconed married in feb 2018. My wife having some extra marital affair which i came to know in march. I object politely so she told me about lady friend but later i came to know that it was her friend's husband. she often used to visit their place and every day on an average of 2 to 3 hours per day she was talking over phone up to mid night and started living in separate room. On 9th may i left my house for my factory while she got herself locked in house and made some injuries ( simple in nature as per medical report) and called 100 and lodge a FIR with some local political support under sec. 323, 342, 354(KH) 498A, 307, 506, 377, Dowry act 3/4 by showing timing 10 AM for whole incident. 15-20 days back she demand on whatsapp for 10 lac for divorce or keep quiet whatever is going on otherwise she will lodge complaint etc. That time in CCTV of PNB bank i was in bank at 10:30 inside bank and 10:13 AM outside bank 18 km from home and mobile location left home at 9:11 AM.
