Deputy Director (public relations) Pranab Kumar Bhattacharya confirmed the matter to media on Thursday.
Pranab said allegations have been raised against 18 hajj agencies.
ACC deputy director Zulfiqar Ali has been assigned to investigate the allegations with director general Mohammad Munir Chowdhury supervising the investigation.
Religious affairs ministry joint secretary Hafizur Rahman told the journalists that the allegations were raised against 18 hajj agencies as 98 pilgrims could not go to Saudi Arabia to perform hajj despite receiving visas.
A general diary has been filed with the airport police station in this regard, he added.
Meanwhile, the parliamentary standing committee on civil aviation and tourism ministry has recommended canceling licenses and imposing fine on those involved in the irregularities of hajj management.
The committee at a meeting on Tuesday made these recommendations.
