The Bangladesh Bank (BB) sought the information by Sunday in a verbal instruction to the banks on April 30.

The National Coordination Committee (NCC) on Combating Corruption and Crime has asked for the information through the central bank, sources said.

Earlier, the central bank directed the commercial banks to submit information on the bank accounts of the two former prime ministers Khaleda Zia and Sheikh Hasina. The commercial banks have already met the central bank directive and the BB has sent the banking information to the NCC, BB sources said.

The commercial banks have so far reported that BNP Chairperson Khaleda Zia and Awami League chief Sheikh Hasina each have about Tk 3 crore in their personal bank accounts.

In addition, both Bangabandhu Memorial Trust and Ziaur Rahman Foundation have some money, but the exact amounts of these funds are yet to be confirmed.

Meanwhile on April 30, National Board of Revenue (NBR) asked all commercial banks for the banking information of 45 people and companies, including Jatiya Party Chairman HM Ershad. The rest include politicians, their relatives and some real estate companies, NBR sources said.

The NBR asked for the information of these people and companies to resolve tax cases against them as it thinks that they have different sources of income, but did not show the sources in their tax returns, the sources added.
