The agency, according to sources, has received a communication from the country's banking regulator-- the Reserve Bank of India regarding a few firms while it has took up the rest casessuo-motofor probe under the provisions of the Foreign Exchange Management Act (FEMA).
A special team of officials of the central probe agency, sources said, is working to study the business operations of these firms which have thronged the online retail marketplace in the last few years.
The sources declined to reveal the identity of the companies under the scanner as the investigations are at a preliminary stage.
According to an official note accessed by PTI, close to a dozen firms are under the scanner of the agency.
There are allegations that the companies have violated the foreign direct investment (FDI) norms of e-commerce sector.
As per the current policy, FDI is not allowed in domestic e-commerce companies conducting B2C (business-to-consumer) transactions while 100 per cent foreign investment is permitted in B2B (business-to-business).
A slew of fund raising and foray of foreign-based investors in these domestic companies has also prompted the enforcement wing of the Finance Ministry to look into their operations in this first time exercise the agency has initiated against online retail and trade companies operating in India, sources said.
The agency, sources added, has gathered documents about the business incorporations, shareholders and business market models of these firms, which include big capital and small online retail firms which are based in major metropolis of the country.
The probe period for investigating the FDI contributions of these firms under the scanner is before April 2013.
Under FEMA rules, a firm or entity found in contravention of the law can be penalised with a penalty three times of the detected violation.
The probe is expected to finish in a "reasonable time period" and in few cases the ED could issue final show cause notices soon.
