Northwest Airlines said on Thursday that its terminal at Detroit Metropolitan Airport has reopened after an unattended package forced its closure.
The No. 5 U.S. airline, which has a hub in Detroit, previously said authorities were investigating the package which was found in a baggage area.
People were evacuated from a 300-foot radius around the area at the McNamara Terminal, according to the reports on local TV and radio, and traffic to an adjacent parking garage was diverted.
It was unclear why the package was considered suspicious, but the terminal's check-in lobby and baggage claim were evacuated, the reports said.
The terminal also serves carriers including Continental Airlines Inc. and Delta Air Lines Inc.
