When Mark Leishman and his wife Kathy first sought out the help of George Dimitriou, they were suffering with cash-flow problems at Mark’s business.

Today, chief investigative reporter Kate McClymont on George Dimitriou, a serial conman and high-school drop-out who conned vulnerable people out of millions of dollars with the help of, allegedly, a bank loans manager, and a series of lawyers.
