Thousands of dollars in counterfeit notes were seized from a traveller who arrived in the United States from Montego Bay, Jamaica, on June 16.

In a statement the U.S. Customs and Border Protection agency (CBP) said officers at Baltimore Washington International Thurgood Marshall Airport seized $7,000 in counterfeit $100 bills from a 64-year-old man.

According to the CBP, officers discovered the counterfeit notes, which closely resembled actual $100 currency, hidden in a sneaker in the man’s baggage during a routine secondary examination.

“Law enforcement knows that counterfeit and fictitious banknotes have been used in financial crimes, especially ones that target our nation’s unwitting seniors, some of whom have lost their entire life savings,” said Keith Fleming, CBP’s Acting Director of Field Operations in Baltimore.

“Customs and Border Protection is committed to working with our law enforcement partners to combat illicit efforts that target our citizens, businesses, and the security of the United States economic system,” added Fleming.

The name of the 64-year-old man was withheld by the CBP, who noted that he had not been criminally charged

Following the seizure of the bills, the man was released.
