(1) Should i wait for notice from police station or no regarding the FIR??? Actually till date i had not received any notice regarding the same. Actually all notice will reaches the old office,where i was worked,may be its possible all notices should be received on that address.
Police will send you the notice after registering the FIR, if you come to know about a pending FIR, in your own interest obtain anticipatory bail and be free from being arrested.
(2) i have my acceptance of resignation letter, NOC certificate etc.
It will not help you or have any impact in the initial stage, so don't be over confident about it.
3) Also i never signed any transaction documents such as banker cheques or any kind of bond/cerificates.
If you have been listed as an accused, you can defend yourself based on the evidences in your possession during trial of the case.
4) Also actually business was on large scale,so there are numbers of FIR having same Charges in various states/police station.should i take bails on all case or there will be any provisions to apply anticipatory bails for all together.
You should obtain anticipatory bail separately on all separate FIRs wherein you have been named as an accused, single anticipatory bail will not protect you from being arrested through another FIR.
