The Anti-Corruption Commission (ACC) has so far frozen bank accounts of some 62 individuals who have close ties with Proshanta Kumar (PK) Haldar.
"The commission has frozen the accounts to recover Tk 10.58 billion laundered by former NRB Global Bank managing director Mr Haldar," ACC secretary Md Anwar Hossain Howlader said on Thursday.
Addressing a briefing at the ACC headquarters, he said an investigation against Mr Haldar is ongoing and the commission has found links of many people with him (Mr Haldar).
"We've interrogated several individuals for their connections with Mr Haldar while two people were arrested on specific information recently," he cited.
About launderers of money to countries like Canada, Australia, Malaysia and Singapore, Mr Howlader said, "We've written to foreign ministry for details on those who bought houses or flats there with laundered money."
The ministry will provide information after collecting it through different agencies concerned, he added.
The ACC has arrested two persons-Abantika Baral and Shankha Bepari-for their close ties with Mr Haldar.
Ms Baral, detained on Wednesday, has been taken on a three-day remand by the commission.
On January 05, the High Court issued a travel ban against 25 associates of Mr Halder, including his mother Lilaboti Halder.
On January 08, the Interpol issued a red notice against Mr Halder, who allegedly laundered more than Tk 100 billion of four non-banking financial institutions abroad.
They are International Leasing and Financial Services Ltd, People's Leasing and Financial Services Ltd, FAS Finance and Investment, and Reliance Finance.
