One of the world’s richest people has been indicted in the U.S. on charges he duped investors in a massive solar energy project in India by concealing that it was being facilitated by an alleged bribery scheme.

Gautam Adani, the world's 18th-richest person, came under scrutiny from both US prosecutors and a major short-selling group in recent years.

U.S. prosecutors allege that Gautam Adani, the second most-wealthy Indian man, personally met with Indian government officials to further their "bribery scheme."
