The EOW of Mumbai police is probing the Hong Kong-based Qnet for an alleged Rs 425-crore fraud.
Gurpreet Singh Anand, who is one of the original complainants against the firm, contends in the fresh complaint that the "purpose of sponsoring IIFA awards is to further the Qnet scam in India and create an image that it is a respectable brand".
IIFA website lists Qnet as one of the 'official direct selling partners'.
The EOW has so far arrested 17 persons for allegedly duping investors by selling Qnet products including magnetic disks, herbal products and holiday schemes through allegedly fraudulent means.
It has been accused of using the banned 'binary pyramid business model', and a case has been registered under the Prize, Chits and Money Circulation Schemes (Banning) Act, 1978.
