The Anti Corruption Commission (ACC) today asked controversial business tycoon and DATCO Group chairman Moosa Bin Shamsher to appear before it on January 28.

The ACC sent a letter to Moosa's office asking him to present himself at the ACC head office at 11 am on January 28 to face its questioning for allegedly acquiring illegal wealth, said ACC public relations officer Pranab Kumar Bhattacharya.

Moosa was scheduled to be grilled on Wednesday. But, on Tuesday he sought time to appear before the ACC saying that he has been suffering from death phobia, high blood pressure and diabetes.

A DATCO Group representative submitted an application inserting a medical certificate to the Commission on Tuesday on behalf of Moosa.

Responding to an ACC directive, Moosa earlier submitted his asset accounts statement to the Commission on June 7, 2015, mentioning his wealth worth US$ 12 billion.

The ACC will question him to take statement on the unusual wealth he mentioned in his wealth report.

On December 14, 2014, the national anti-graft body also interrogated Moosa and he claimed that a huge amount of his money remains frozen in Swiss bank.

Moosa Bin Shamsher featured in cover stories of The Sunday Telegraph Magazine (London) and many other business magazines, including Business Asia, revealing that he has accumulated wealth worth about US$ 7 billion.

Considering the reports published in international media about his lifestyle, income and income sources, the ACC on November 3, 2014, decided to launch a probe against him who is believed to have made his fortune selling arms during the Iran-Iraq war.

Moosa, a pioneer of manpower export from Bangladesh, has drawn flak for purportedly being a prominent name in the international arms industry during the 1970s and 1980s.

It is alleged that Moosa has a Swiss bank account with US$ 7 billion frozen in it because of 'irregular' transactions.
