Love married wife as per her dad's intruction filed criminal case againt husband

Mine was Love marriage and registered in muslim jamath which was against her family. We lived together away from her family. She got pregnant and wanted to visit home. The moment she visited and stayed for a while. Then after some days, she asked me to bring her. Whils i was stepping her home, police jeep was there already there in the street near her home. I ignored and when i entered her home at 1300 hrs, police got inside and assaulted me and brought me to police station and taken my mobile and then she came with her dad and she filed a complaint against me and i was charged criminal case as per IPC 294, 323, 506(ii), TNWH 4. Her dad asked me to sign Khula divorce mentioning they found anothed alliance and hence i have no rights over the child in the womb. I strongly refused and they assaulted saying they would withdraw the case if i signed and go away. But i determined not to sign.they waited till 2000 hrs and remanded me in prison by having me appeared at magistrate home at 2100 hrs. I came out on bail. Bit they have shifted their rental home and brought my wife and child along with them. When i called them, threaten that they would file another fake charges if i try to meet my wife and child. They also changed my mail id by using my mobile OTP while i was i prison and they could misuse my mail for cyber crime and put foist charges again.The case is adjourned to March 9th 2020. I could not meet my child. They have police influence to put another foist charges if i go to complain in police station. Kindly advise. Thanks
