rajaramana rv ji, 1st of all NBWs are issued in order to make the accused appear in court, as my learned friends above have already advised you, that you should appear before the magistrate and pray for cancellation of NBW. go to a lawyer hire him and let him find out the details. you can also go to the district court which monitors the police station nearest to you and ask the court staff to help you. the district court must be having a help desk, they will help you locate the court. once you reach the court where the case is going on or was on, u can ask the staff there to help you out. it is best that you let the experts handle this, find a good lawyer and let him do the work. our advice can help you, but its always best to let the expert handle the work. one mistake and you will be arrested.
