Bangladesh Financial Intelligence Unit today asked banks to provide detailed information of accounts and transactions of Sayeed Khokon, former mayor of Dhaka South City Corporation.

The intelligence agency, dedicated to tackling money laundering and terrorist financing, asked the banks to provide information within three working days.

Despite repeated attempts, The Daily Star could not reach Khokon for comments.

Last month, a Dhaka court ordered to freeze eight bank accounts of Sayeed Khokon and three of his family members -- wife Farhana Alam, sister Shahana Hanif and mother Fatema Hanif -- as part of investigation into allegation of "amassing illegal wealth".

Of them, three accounts belong to Khokon's business firms, two accounts belong to his wife, two accounts belong to his sister, and one belongs to his mother.

The court passed the order after a deputy director of the Anti-Corruption Commission, who is also head of the enquiry team, submitted an application seeking permission for freezing their bank accounts in this regard.

On December 29 last year, Sayeed Khokon and six others were sued on charges of embezzlement of around Tk 35 crore.

Md Delwar Hossain, president of businessmen, owners' association of Fulbaria City Supermarket-2 in Gulistan, filed the case with the Chief Metropolitan Magistrate's Court of Dhaka.

The case is now under investigation.
