DETROIT, Sep 13 (Reuters) Authorities briefly shut down the main terminal at Detroit Metropolitan Airport today morning after a package in a cargo area triggered a security alert, officials aid.
Police determined the package not dangerous and authorities reopened the terminal after an hour, airport spokesman Michael Conway said.
Conway declined to identify what was in the package, which he said had been delivered by a truck to a cargo dock on the lowest level of the three-level terminal, which serves as the Northwest Airlines Corp hub in Detroit.
''We evacuated everyone to a 300-foot perimeter, which is in line with protocol,'' he said.
A spokeswoman for the Transportation Security Administration, Lara Uselding, said a bomb-sniffing dog ''hit'' on the package, triggering the security alert.
The McNamara terminal is the busiest at Detroit's airport. The FAA, which monitors air traffic, said it did not expect delays as a result of the brief evacuation.
