Federal Agents found 93 bundles of counterfeit $100 bills and 32 bundles of Vietnamese currency on Friday at the Detroit Metro Airport.

U.S. Customs and Border Protection says that its agents seized more than $4.6 million worth of counterfeit bills from a Vietnamese couple after returning from Seoul Korea. Officers stated the couple was detained on Friday, and found the stacks of counterfeit cash.

Officers report that the couple stated they intended to burn the cash as part of an offering for a cultural ceremony. Of course that was not a good enough reason for the couple to continue their journey, so they were detained. Federal agents stated regardless of religious or cultural purposes, it's illegal to import counterfeit currency.
