Buried in an 85-page document, was a diagram of seven unlisted firms registered in the British Virgin Islands, Mauritius and Dubai. They were interlinked to each other, and one would be buying the cement company’s shares in the open market.

Instead, the filings said their beneficial owners were his older brother, Vinod, and Vinod’s wife Ranjanben.
