Fir for fraud in banking transaction

It is not possible to say anything without knowing what exactly happened and your explanation for it. You have paid the bank. But somewhere someone has made an illegal gain. That person has to be caught. You co-operate with the bank and the police to catch the culprit. Unless you give details we cannot know who and where is the culprint.

You have deposited the money.

You may Co-operate in inquiry by police.

You need to come clean in internal inquiry by Bank.

Bank per IT's rules may not want to let deliquent employee escape.

It shall be in your interest to seek support of very able senior LOCAL counsel of unshakable repute and integrity specializing in service matters, defense assistant  having successful track record in such matters.

If a loss is suffered by a party due to theft or fraud the case for criminal offence doesn't stop if the money or property is returned except for VIP's like late Jayalalitha (Tansi case). Criminal proceedings by police and court can continue. Engage a lawyer like  Adv. Tulasi to bail you out. Tulasi bailed out Jayalalitha.

On website of local police commissionerate easy descripttion of section and offences is published and the instances under which police can arrest.

Rest; discuss with Local counsel and defense assistant and understand the gravity and remedies.

If you wish to separate and can separate, explore the options. 

If you wish to come clean out of the issue, explore the options. 

See bro, the problem is that you haven't explained what exactly took place and how that happended. So i think it is too early to say anything about such a case
