The Anti-Corruption Commission on Monday decided to start investigating the people who earned their wealth through the illegal casino business.
The decision was taken at an emergency meeting of the commission, said secretary Dilwar Bakth during a press briefing at its Segunbagicha headquarters.
Syed Iqbal Hossain, a director of the commission, was appointed as the inquiry officer in this regard, said Dilwar.
"We are scrutinizing documents related to Bangladesh Chhatra League former general secretary Siddiqui Nazmul Alam," the secretary added.
Nazmul came under the limelight after different media portals published that he has illegal wealth stashed abroad.
The law enforcement agencies started a crackdown against casino and other related illegal businesses in line with Prime Minister Sheikh Hasina's directives.
During a drive on September 18, law enforcement arrested Dhaka South city unit Jubo League Organising Secretary, Khaled Mahmud Bhuiyan, for running a casino out of a sporting club in the capital.
Another Jubo League leader, GK Shamim, was also arrested on September 20, for his alleged involvement in criminal activities and tender manipulation.
Additionally, a number of leaders of the Jubo League, Krishak League and the Awami League were detained following Khaled's arrest.
