Bank fraud case which has been handed over to CBI later

My father was bank manager and some people opened loan/current account with fake documents in year 2004 in several branches. Through which 30akh rs had been withdrawn and all documents used to open an account was found fake. In 2006, Chairman of bank has filled a case in CBI for enquiry, apart from this bank has also conducted an internal bank enquiry and removed my father(bank manager from service) and withhold his salary account including FDs and gratuity. In 2014, my father expired due to some illness and in 2021, CBI court has passed an order in this case as 3 year jail to all branch managers where fraud has been done. Now my question is what will happen to the salary account amount and FD amount now which is still under the custody of bank? How can we claim it now.
