Filing case on criminal intidimation

Did you file any complaiint against your FIL's elder brother earlier? If yes what is the result, if no, file it now. Ask for police protection and avail if you can get it.

No I haven't filed any complaint against him yet. Should I be filing the complaint where i stay (chennai) or where he stays (Bhavnagar)? What evidence does the police require? Is mere FIR necessary to arrest him or there will be enquiry, investigation, charge sheet and then arrest. There is a high possibility that he may shift to US by end of this month.

cause of action arose in bhavnagar, so u have to file (complaint) there only. Since you say he is native of that town police will resist to take action immediately. 

You have not stated whether he threatened you in front of you or through phone.  File a police complaint in Bhavnagar.  If he has threatened you through phone when you are residing in Chennai, you have to file in Channai. You can also file under cyber crimes also. 

 

You said that he was earlier a goon and having political contacts.  Then he might have managed the local PS.  You have to approach DCP or Commissioner of Police. You will get prompt relief. 

When I went to Bhavnagar to pick up my wife. He told me this in person in front of my father in law. However father in law is in his side. What should be the course of Action? My in laws screwed my whole career. I lost my job. I cannot go abroad due to section 125 filed in my name. Should commissioner of police Bhavnagar require any documentary proof or any evidence to arrest the accused or will there be initial inquiry and then arrest.
