The National Board of Revenue (NBR) on Wednesday asked banks to freeze all accounts of former Bangladesh Bank (BB) deputy governor SK Sur Chowdhury and his wife Suparna Sur Chowdhury for suspected tax evasion. Central Intelligence Cell of the revenue collecting authority, in a letter, directed all banks to freeze withdrawal or transfer of money from all accounts maintained by  them. The NBR CIC gave the directive to the banks suspecting of tax evasion by the couple. The CIC also asked banks to submit a compliance report, stating the latest balance of the accounts. On February 23, the NBR has asked banks for detailed information of all types of accounts and transactions of five people, including  SK Sur Chowdhury, present Executive Director of Bangladesh Bank Md Shah Alam and their spouses.
