How to sue the bank which falsely accused me based on forged documents?

The Bank filed a false case against me and when I visited the bank's legal team I found that all my documents were forged and the loan was processed. I suffered in jail for one day and then the case was withdrawn by the bank.

How to demand an explanation and compensation from the bank? Am I eligible to sue the bank?

I'm currently financially weak and would like to pay the lawyer fees after getting any compensation. I have proof of forged documents.
