3 After doing the preliminary enquiry and recording the statements of victim and accused , if police thinks that prima facie, case is made out , then registration of FIR happens.
4 As per the nature of complaint and allegation made , the FIR gets registered under both IT Act and IPC.
5 If the sections are bailable, bail is granted from the police station itself but the trial will begin in courts and you will get chance to book home the culprit.
6 If non bailable then the immediate arrests of the accused happen. He may try for anticipatory or Interim Bail as this is his/her right but you can contest it and assure the the Bail is not granted to him in any case.
