United States Customs and Border Protection (CBP) is reporting the seizure of over a million dollars in currency at the Blue Water Bridge.
On August 22, officials confiscated the funds from a U.S. citizen after he failed to report the money.
CBP said the male traveller and his family arrived in Port Huron after being refused entry into Canada. He initially denied carrying more than $10,000 to officials but, when given another chance, changed his declaration to $990,000.
Further inspection by CBP officers led to the discovery of two safes containing $1,096,584.
"There is no limit as to how much currency travellers can import or export as long as it is accurately declared to CBP," said acting Port Director Geoffrey Stoffel.
Currency reporting rules require travellers to declare when they transport more than $10,000 in funds when travelling into or outside of the United States.
Violators may face criminal penalties and forfeiture of the undisclosed funds.
