Con men swindle Atlantic City casinos out of millions

According to investigators, a group of con men originally from Bangladesh came to New York City and targeted Atlantic City casinos. The men then used casino global cash machines, meant for higher rollers, to steal millions.

"The casinos unwittingly were facilitating the activity because that type of transaction is what the casinos rely on," said New York's Homeland Security Special Agent in Charge James Hayes. He estimates various banks were robbed of millions.

CNBC's Crime & Punishment rode along with Homeland Security agents to get an inside look at how the con men pulled off the scam.
