The accused, Md Amirul Islam, an assistant director stationed in Rajshahi, was suspended on Monday, an official told bdnews24.com.
He said it has been proved in initial investigation that Amirul acquired around Tk 20 million of wealth from unknown sources and concealed the information.
Another official, ACC Director General Munir Chowdhury, told bdnews24.com, "Amirul would face the same action other citizens face on similar charges."
In an office order, ACC Acting Chairman Nasiruddin Ahmed said Amirul showed zero bank balance in his income tax return, but the ACC found he had deposited around Tk 1.3 million in his Sonali Bank.
The ACC also found that he had bought his wife 1.3 acres of land worth Tk 17.5 million in Gazipur and Tangail and concealed the information in his official records.
He could not clarify the source of this money, according to the order.
