who is required to file suspicious activity reports
Suspicious activity report In financial regulation, a Suspicious Activity Report (SAR) or Suspicious Transaction Report (STR) is a report made by a financial institution about suspicious or potentially suspicious activity. The criteria to decide when a report must be made varies from country to country but generally is any financial transaction that does not make sense to the financial institution, is unusual for that particular client or appears to be done only for the purpose of hiding or obfuscating a transaction. The report is filed with that country's financial crime enforcement unit, which is typically a specialist agency designed to collect and analyse transactions and report these to relevant law enforcement units. Front line staff in the financial institution have the responsibility to identify transactions that may be suspicious and these are reported to a designated person that is responsible for the reporting the transaction. The financial institution is not allowed to inform the client or the parties to the transaction that a SAR has been lodged.
Law enforcement in the United States Law enforcement operates primarily through governmental police agencies. The law-enforcement purposes of these agencies are the investigation of suspected criminal activity, referral of the results of investigations to the courts, and the temporary detention of suspected criminals pending judicial action. Law enforcement agencies, to varying degrees at different levels of government and in different agencies, are also commonly charged with the responsibilities of deterring criminal activity and preventing the successful commission of crimes in progress. Other duties may include the service and enforcement of warrants, writs, and other orders of the courts.
