DETROIT — More than 1,000 pounds of cocaine and 972 pounds of methamphetamine were seized last week by authorities at the Ambassador and Blue Water bridges, officials said.

A commercial vehicle bound for Canada was selected for examination on Thursday at the Ambassador Bridge in Detroit, according to U.S. Customs and Border Protection officers.

They searched the truck's trailer and found several bricks of a white powdery substance concealed within multiple boxes and two duffel bags, investigators said.

Officials said the suspected narcotics, the truck, and the trailer were seized. The driver, a citizen of India, was arrested. Testing confirmed the substance to be cocaine, according to authorities.

"Preventing the scourge of dangerous narcotics from harming our communities is an essential part of our border security mission, and we'll continue to hold the line against the illicit drug trade," Customs and Border Protection's Port of Detroit Director Marc Calixte said in a statement.

Authorities said CBP and Homeland Security Investigations officers searched a Canada-bound truck at the Blue Water Bridge in Port Huron on the same day and found suspected methamphetamine.

Officers with canine units found 400 bags of a substance, which was seized and later confirmed to be methamphetamine through testing.

They arrested the driver, a Canadian national, and seized his truck.

"This case is a testament to the collaborative effort put forth by CBP officers and our law enforcement partners each day to protect the homeland," Customs and Border Protection's Port of Port Huron Director Jeffrey Wilson said in a statement.

Both cases remain under investigation by U.S. Immigration and Customs Enforcement's Homeland Security Investigations.

"The combined and focused efforts of HSI and CBP are dismantling drug trafficking networks along our Northern border," Acting Special Agent in Charge of ICE HSI Detroit Matthew Stentz said in a statement. "We continue to work closely with our federal, state, local, and Canadian partners to stop the flow of illicit narcotics and provide for our common safety on both sides of the border."

Officials said the CBP's Detroit Field Office seized more than 4,300 pounds of cocaine and nearly 1,000 pounds of methamphetamine so far during its 2025 fiscal year.

The two drug seizures are the latest made at Michigan's border with Canada.

Last month, Canadian authorities seized more than 769 pounds of suspected cocaine at the Blue Water Bridge, they said last week.

In July, they seized more than 434 pounds of cocaine at the Blue Water Bridge, they said last month.

Canadian authorities said they seized more than 400 pounds of cocaine at the bridge in June.

In March, U.S. Customs and Border Protection officers seized more than 115 pounds of cocaine at the Ambassador Bridge.
