REPORTING OF SUSPICIOUS TRANSACTIONS [https://www.fatf- gafi.org/media/fatf/documents/recommendations/pdfs/FATF%20Recommendations%202012.pdf] If a financial institution suspects or has reasonable grounds to suspect that funds are the proceeds of a criminal activity, or are related to terrorist financing, it should be required, by law, to report promptly its suspicions to the financial intelligence unit (FIU). According to the Financial Action Task Force‘s (FATF) Recommendation 20, a suspicious transaction report (STR) or a suspicious activity report (SAR) is filed by a financial institution or, by a concerned citizen, to the local Financial Intelligence Unit if they have reasonable grounds to believe that a transaction is related to criminal activity.
