Upon launching an investigation, they realized that a lot of Rials were being routed to the Port City of Aden. It was found that a young man in his twenties was placing unlimited buy orders for Yemini Rials.During those days, the Yemini Rial was made of pure silver coins and was in much demand at the London Bullion Exchange. Young Dhirubhai bought the Rials, melted them into pure silver and sold it to the bullion traders in London. During the latter part of his life, while talking to reporters, it is believed that he said “The margins were small but it was money for jam. After three months, it was stopped. But I made a few lakhs. In short, I was a manipulator. A very good manipulator. But I don’t believe in not taking opportunities.
