Dear Madam,
You can lodge complaint at any of the convenient police stations since police people have to investigate the case at both the places. It is better to file complaint at Bhubaneswar. The police may register the case and issue FIR for the following offences. If for any reason they did not register then you may file a private complaint before Magistrate under section 200 Cr.P.C or may directly approach the High Court under section 482 Cr.P.C. You have to explain the delay and also enclose PM report if any. All the 10 persons to be named in your complaint and there will be booked for the following offences read with section 149 IPC. I have worked as Magistrate for 20 years and if you get any doubt you may call me.
