The Ministry of Corporate Affairs has launched an investigation into the financial accounts of two airports in Mumbai operated by Adani Enterprises. The company has confirmed the news, saying that the ministry has asked it to submit documents regarding Mumbai International Airport Ltd and Navi Mumbai International Airport Ltd for the financial years 2017-18 to 2021-22.

The Adani Group has not responded to a Reuters request for further details. The Indian Corporate Affairs Ministry has been scrutinizing the Adani Group”s financial statements since February. The latest developments come after an Organised Crime and Corruption Reporting Project (OCCRP) report showed that the Adani Group imported coal at exorbitant prices.

The Adani Group controls seven airports in India, six of which were acquired under the government”s initial privatization initiative. The Chhatrapati Shivaji Maharaj International Airport in Mumbai was acquired in 2021, and a new airport is under construction in Navi Mumbai.

The latest probe is one of a series that the Adani Group has been undergoing since a US short-seller released serious allegations against it on January 24. Hindenburg accused the Adani Group of illegally using offshore tax havens and manipulating stocks.

In May, a court-appointed committee stated that an investigation by India”s markets regulator into these allegations had not produced any results. However, last week, Reuters reported that the financial regulator would clarify to the country”s highest court why it had stopped and then resumed investigations into the group after receiving a tip in 2014, due to concerns about regulatory delays.
