The chief of Bangladesh's Anti-Corruption Commission (ACC) has said that many more arrests can be expected in the coming months.
Former minister Amanullah Aman has been sent to prison in the drive
Hasan Mashhud Chowdhury told the BBC some 200 people had been questioned or detained awaiting trial so far.
They include politicians, officials and businessmen.
The drive against corruption was launched six months ago. It comes ahead of planned elections promised by the caretaker government by December 2008.
The military-backed government which took power six months ago has made cracking down on graft its priority.
So far, dozens of former MPs, many of them ex-ministers, have been locked up and are now awaiting trial.
Mr Chowdhury said his mission was to bring to justice those who had abused their positions to accrue massive wealth.
He insisted that due process is being followed, but some observers say it is time to lift the emergency powers to ensure the restoration of full rights to all citizens, including those accused of corruption.
