The Anti-Corruption Commission (ACC) summoned lawmaker Mahi B Chowdhury and his wife Ashfah Haque Lopa for interrogation over their alleged involvement in money laundering and amassing illegal wealth.
A letter, signed by ACC Deputy Director Jalal Uddin Ahmed, was sent to the couple on Sunday.
They were asked to be present at the ACC headquarters at 10am on August 7.
The letter said that there are allegations against Mahi B Chowdhury that he laundered money to the United States and amassed illegal wealth.
They have been called to identify the source of the money, an ACC official said.
The ACC is also taking support and assistance from different banks and other institutions to obtain detailed information about the wealth of Mahi and his wife.
Mahi is a son of former president AQM Badruddoza Chowdhury and also the joint secretary general of Bikalpadhara Bangladesh.
