The central bank’s Bangladesh Financial Intelligence Unit (BFIU) sent letters to the banks asking for the information.
The 11 DIP officials are Director General NM Zeaul Alam, directors Munshi Muyeed Ekram and SM Nazrul Islam, assistant directors SM Shah Zaman, Umme Kulsum, officials Shahjahan Mia, Saiful Islam-1, Rafikul Islam, Abdul Mabud, Syed Ahsan Habib and Noor-e-Alam Chowdhury.
The banks were ordered to send details within seven working days.
Recently Turkey alleged that many from Bangladesh with official passports did not return.
It also gave a list of such Bangladeshis to the foreign ministry.
The home ministry launched an investigation following the Turkish allegation.
It was found in the investigation that people other than public servants were issued official passports.
The DIP then suspended directors Ekram, Nazrul Islam, Assistant Director Zaman, and officials Mia and Saiful Islam.
