Authorities say they still haven't determined what caused six U.S. border agents to require decontamination and medical attention after inspecting a vehicle at a crossing in northern New York.
Customs and Border Protection officials say two officers were examining a 2002 BMW around 6 a.m. Saturday at the Champlain crossing when they began to feel ill. Four other officers who went to help them didn't become sick.
State and local hazardous materials teams responded. Officials say all six officers were decontaminated on site and taken to the hospital in Plattsburgh. They were later released.
Clinton County emergency services officials say Monday they still don't know what caused the two officers to become ill. The case is being investigated by state police, who haven't released any information.
