Bank Fraud Investigations
What is Bank Fraud?
Bank fraud is the use of illegal means to obtain money, assets, or property owned or held by a financial institution. Fraudsters may falsify documents, forge signatures, or use deceit to misappropriate funds.
Key Elements in Bank Fraud Investigations
Complaint and Detection
Initiated by internal bank audits, customer complaints, or regulatory agencies.
Preliminary Inquiry
Conducted by internal audit teams or vigilance departments to assess prima facie evidence.
Formal Investigation
Handled by agencies like the CBI (in India), FBI (in the US), or other financial intelligence units.
Includes forensic audits, review of account statements, interviews with suspects, and digital forensic analysis.
Filing FIR/Chargesheet
Once sufficient evidence is gathered, an FIR is filed, and a chargesheet is submitted to court.
Prosecution and Trial
Prosecution presents evidence; defense contests based on law and fact. Judgment is rendered by the court.
