Nothing about the content of the report could be known immediately.

The committee was asked to look into how the illegal payment instructions were issued from Bangladesh Bank and to whom, and examine whether the steps taken by the central bank to prevent the payment were appropriate. It was also asked to evaluate the reasons behind concealing the information on the heist from higher authorities.

Cyber criminals stole $101 million from Bangladesh Bank's account with New York's Federal Reserve Bank in February. The incident came to light several days later.
