Divorce case

Have received call from thane crime branch statimg i have be presented as my first wife had file complaint against me.they didnt diclose anything abt complaint . Just for information i m a muslim this women left me 2 years back staying she wanted me to leave my parents. I tried solving the difference but she was not ready. Then i did second marrige as per shariat law.now she is claiming cheating case and asking for 7 lac rs to sertle the matter outside the court. My question is there any chances that police may arrest me if yes how can i immediatly get bail. As second marrige without first wife consent is allowedin shariat and muslim personal law can this be an issue.can she put baigamy case on is that valid for muslims in india. How soon can i get bail if they arrest. Can they arrest me without arrest warrant. I m ready to keep her and dnt want divorce andshe also in her concerstaion said she wants to leave with me and dnt have any problem with my second marrige which i have the recordind. Please suggest what can be done in my case to avoid arrest
