The U.S. indictment of Gautam Adani has thrown a spotlight onto the rolling risks of India’s solar industry. Last week, prosecutors in New York charged the billionaire and several others of securities and wire fraud by agreeing to bribe government officials to secure solar power contracts for the Adani Group’s $19 billion renewable energy unit.

Adani, 62, one of Asia’s richest men, was thrust into the spotlight last week when U.S. prosecutors in New York charged him and seven of his associates with securities fraud.

Adani Green Energy said that contrary to media reports, its chairman Gautam Adani and his aides have not been charged for violating the U.S. Foreign Corrupt Practices Act.
