The case reads like an "Indiana Jones" movie script. A New York City antiquities dealer raids archaeological sites and temples in India, Pakistan and Cambodia, and then smuggles the pieces into the United States, where they're sold for millions of dollars.

According to federal authorities, that's exactly what Subhash Kapoor did. The 64-year-old Kapoor is accused of stealing hundreds of pieces of art valued at more than $100 million, according to James Dinkins, a director of Homeland Security Investigations. That department is overseeing the case involving one of the largest art rings. "This is definitely one of the biggest, I think that we've seen in the world," Dinkins told CNBC.
