Walmart-owned Flipkart and Amazon, both of which are experiencing rapid growth in India's Rs 70 billion e-commerce market, face rising regulatory scrutiny.

India's financial crime agency is intensifying its investigation into Flipkart and Amazon for alleged foreign investment law violations. This follows recent raids on sellers associated with these e-commerce giants.

India's financial crime agency has raided offices of some sellers operating Amazon and Walmart-owned Flipkart in an investigation into alleged violations of foreign investment rules, three government sources said on Thursday.

The Enforcement Directorate (ED) will summon Flipkart and Amazon executives as part of its probe on foreign investment rule violations. The financial crime agency will probe five years of data.
