Authorities are investigating what made six U.S. border patrol officers to become ill while inspecting a vehicle at a border crossing in northern New York.
Clinton County emergency services officials tell local media outlets that the vehicle was being inspected at the Champlain crossing on the U.S.-Canadian border around 6:30 a.m. Saturday when six officers became ill because of an unknown substance.
All six were sent to the hospital in nearby Plattsburgh, where they were later released. Authorities say there was no danger to the public at any time.
Officials say the driver of the vehicle was questioned.
No other information has been released Sunday. Messages left with U.S. Immigration and Customs Enforcement weren't immediately returned.
