India's market regulator is investigating the funds identified by a non-profit media organization, which allegedly invested millions in publicly traded stocks of India's Adani Group, according to sources familiar with the situation.

The Organized Crime and Corruption Reporting Project (OCCRP) revealed that offshore entities based in Mauritius acquired 8% to 14% of shares in four Adani Group subsidiaries: Adani Power, Adani Enterprises, Adani Ports, and Adani Transmissions. The Adani Group has refuted these claims. The funds implicated are already part of an ongoing regulatory inquiry into the Adani Group's potential violations of public float norms. Any new information will reportedly be incorporated into the ongoing investigation, the sources noted.
