Can I file a case against General Manager of my Company (a Bank)? I am an employee of the same bank.

Hello Sir/Madam, I am working in a Bank as a manager. I have been verbally instructed My regional Zonal Manager to grant some loan in the unethical manner which I said no. Now he is creating problems from back. After checking many different accounts of customers in different branches, I got to know he has granted loans to hide the NPAs and also has granted fresh loans to clear the existing NPA loans within the bank. This way I think he has misused the public funds to get the promotion and to show his performance (he is the fastest promoted person in the bank). I wrote the matter to my MD anonymously on that he conducted inquiry in which ZM found guilty. But due to his terms with other Directors nothing happened. I have copy of all the accounts statement he was routing the funds in a particular numbers of accounts with the cooperation of 4-5 branches. Now please guide me, 1.) Can I file a civil case against the ZM in public interest ? 2.) Can I file the case from my native place around 1500 KM form present location. (as I think I will be fired or suspended from the service once I sue him. And It will be hard for me to stay without JOB). 3.) Whether Sec 409 and 420 of IPC is applicable?. Thank You.
