The Anti-Corruption Commission (ACC) yesterday quizzed six people, including former managing director of Farmers Bank SK M Shamim, for around six hours in connection with an ongoing enquiry into “suspicious transaction of Tk 4 crore in a bank”.

The ACC also quizzed Farmer Bank's former head of business Gazi Salauddin, First Vice President Swapan Kumar Roy, former manager (operations) Lutful Haque, Credit In-Charge Shafiuddin Ahmed and Executive Officer Umme Salma at its Segunbagicha headquarters.

The commission has also asked the Special Branch of police to take steps to prevent them from leaving the country, said Pranab Kumar Bhattacharya, ACC's public relations officer.

The anti-graft watchdog quizzed them in connection with the “Tk 4 crore suspicious transaction in the account of a very important personality of the country”.

Speaking anonymously, an ACC official said the very important person is former chief justice SK Sinha.

Reporters approached the six for comments as they were leaving the ACC interrogation cell, but they left in a hurry without responding.
