ACC public relations officer Pranab Kumar Bhattacharya said Enamul was supposed to appear before the national anti-graft body on Monday afternoon but he sought time citing illness.
Basir was suspended on June 10 for allegedly leaking information, a breach of job discipline.
According to a report run by a private TV, Enamul Basir, who was assigned to look into the corruption allegation against DIG Mizan, took Tk 40 lakh as bribe from him with a promise to give him a clean chit.
Later, the ACC formed a three-member inquiry committee with Fanafillah as its head to look into the matter.
After reviewing the committee’s findings, the national anti-graft body suspended Basir on charges of illegally transmitting its data and violating the job discipline.
It also imposed a travel ban on him.
