As per paragraph 22.2.10 of the Policy Document, where an STR has been lodged, reporting institutions may opt to update or make a fresh STR as and when a new suspicion arises.

Reporting institutions are encouraged to submit a new STR if there is new critical information. Where a new STR is submitted, reporting institutions should include the previous reference number as part of the reporting description.

These reports and supporting documents are to be kept for at least 6 years, as specified under Record Keeping in paragraph 24.3 of the Policy Document.
