Bangladesh Financial Intelligence Unit (BFIU) has instructed banks and financial institutions to provide the account details of former Energy and Mineral Resources Adviser Tawfiq-e-Elahi Chowdhury, Bir Bikram, and Awami League Joint Secretary AFM Bahauddin Nasim.

The BFIU's request, issued on Tuesday, also seeks the financial information of Nasim's wife, Sultana Shamima Chowdhury, and their son and daughter, ABM Siddique and Nuzhat Tabassum.

In a letter to the financial institutions, the BFIU noted that the provisions of the Prevention of Money Laundering Act would apply to these accounts. The institutions have been directed to submit documents such as account opening forms, Know Your Customer (KYC) details, and transaction statements within two working days of the letter's issuance.

This request comes as part of an ongoing investigation. Tawfiq-e-Elahi Chowdhury was arrested last month and remains in custody.
