You have said that the police has been asked by the court to conduct further investigation.
It is not clear whether the police is recording statements of your bankers, clients, demat service providers, in your case only or in some other case. Or, else, how the police is harassing them or conducting investigation, it is not clear.
You should try to ascertain whether the police is conducting investigation in your case and have registered some other FIR (against you or some other person).
Police can conduct investigation in all aspects of the case. If you feel that the police is deliberately doing the investigation wrongly, you can always bring it to the notice of the senior police officers or to the court which directed further investigation.
