According to the Certified Anti-Money Laundering Specialist (CAMS) Sixth Edition manual, the AML compliance officer should inform senior leadership and the board of the investigation (page 124) and monitor the progress of the investigation by keeping clear records (page 127). Additionally, the AML compliance officer should provide all information to the FIU as soon as possible to avoid delays (page 126).
According to the CAMS Manual, when a financial institution is being investigated by the financial intelligence unit (FIU), the AML compliance officer should inform senior leadership and the board of the investigation and monitor the progress of the investigation by keeping clear records. The manual states:
"The AML compliance officer should inform senior leadership and the board of any investigations and then monitor the progress of the investigation by keeping clear records of what has been requested and submitted, deadlines and extensions granted, and any findings or reports received. This will allow the financial institution to respond effectively and efficiently to the investigation and take appropriate action if necessary." (CAMS Manual, Section 7.4.1 - Financial Intelligence Units, p. 366)

The primary consideration the institution should keep in mind when deciding whether to agree to the law enforcement request is whether the institution can continue to meet its regulatory obligations with the accounts open. This is because the institution has a duty to comply with the applicable laws and regulations, and to protect its reputation and integrity from being associated with money laundering or terrorist financing.
The institution should assess the risks and benefits of keeping the account open, and consult with its legal counsel and senior management before making a decision. The institution should also document itsdecision and the rationale behind it, and communicate it to the law enforcement agency12.

According to the web sources I found, FATF Recommendation 18 requires financial institutions to implement group-wide programmes against money laundering and terrorist financing that include policies and procedures for sharing information within the group for AML/CFT purposes12. These programmes should also include compliance management arrangements, screening procedures for hiring employees, an independent audit function and ongoing employee training1.
