Dr. Moosa Bin Shamsher is a Bangladeshi business tycoon known for being a major player in international arms trading during the 1970s and 1980s (as well as for many other business ventures). Affectionately dubbed “Prince Moosa” by the South Asian press, this high-profile figure is, notwithstanding, known for dealings with other shady big name arms dealers on this list such as Adnan Khashoggi and Sarkis Soghanalian. It is also alleged that Shamsher has had Swiss bank accounts worth $7 million frozen because of “irregular” transactions. Formed in 1974, Shamsher’s business, DATCO, deals in global weaponry, including tanks, fighter planes and ballistic missiles. Almost as renowned as Shamsher’s arms dealings is his love of excess: he owns a fleet of a hundred private cars that includes Rolls-Royce models and limousines and wears diamond-encrusted shoes valued at $3 million.
