Four weapons were found in a car after Canadian officials at a border crossing became suspicious of the driver, authorities said.
The firearms — a 9 mm handgun, two shotguns and a rifle — were found in a car that had just passed through the Peace Arch border crossing at about 9:30 p.m., Royal Canadian Mounted Police said in a statement.
RCMP initially said a device found in the car’s engine compartment was an improvised explosive device but later said it was not a bomb after an explosives team examined it.
The device “had some wires protruding from it and was suspicious in nature,” according to a statement signed by RCMP Cpl. Roger Morrow.
Interstate 5 in the United States and Highway 99 in Canada were closed at the crossing — the busiest between the two countries west of Detroit — until midnight then reopened.
The discovery was made after officials became suspicious of the passenger car, which was occupied only by the driver, a man who was acting erratically, said Paula Shore, spokeswoman for the Canada Border Services Agency. The Mounties’ explosives squad was summoned, she said.
The man, whose parents live in Oregon, was turned over to the Canada Border Services Agency, said Paula Shore, a spokeswoman for the agency.
No criminal charges were planned and the man was expected to be returned to the United States, officials said.
“It appears as though the male is suffering from a mental illness,” Morrow said in the statement.
