The Tran Organisation were a criminal gang operating in the 2000s. Led by Van Thu Tran they embedded themselves into US casinos, originally hatching the plan as a husband and wife team at Tribal casino in San Diego, California. With knowledge of the low wages and low hours they took to trying to bring numerous dealers and table supervisors into their plan.
The plan involved one member of the team noting down all of the hands that came out, and a dealer who performed a false shuffle. A series of earpieces and microphones meant that members of the origination had a keen awareness of which hands would be coming out.
They were eventually found out and Van Thu Tran received a three year prison sentence and had to pay back several million dollars.
