When the case against you was initiated, you were facing two actions, i.e. departmental and criminal. The Bank has exonerated you from the departmental action but the police has found the offence proved against you, hen they filed a charge sheet against you.
Now you will need to fight the trial before the trial court. However, it appears that the Bank is on your side. So you may try to get the offence u/s 406 compounded by compromising the matter with the complainant. The Bank is the complainant in the matter so it should not be difficult.
