The agency, as part of its FEMA probe, has written to agencies like the Income Tax department, RBI and the Registrar of Companies (RoC) to obtain detailed information about the operations of the Rajasthan registered firm, said to be owned by Modi and his family members.
Sources said the agency may also get in touch with their counterparts in Mauritius to obtain details on the incorporation of a suspected firm there which allegedly sent funds to the Indian company.
The case pertains to the routing of the amount a few years ago into this firm in alleged contravention of the Foreign Exchange Management Act (FEMA).
The sources said the present and past executives of the said firm would soon be called for questioning and even Modi could be served summons at a later stage for recording of his statement.
The ED had begun investigations into this case in October last year after it detected some foreign investment coming into this group which had Modi's relatives at the helm.
The agency has already recorded the statements of few executives of the said firm.
