CHICAGO (WLS) -- A cargo building at O'Hare International Airport was evacuated early due to a suspicious package, but has since reopened.
The cargo building was evacuated around 12:40 a.m. Thursday and was reopened about two hours later. The box contained computer drives, officials said, and was not dangerous.
The Bomb and Arson Unit was called to the scene and the hard drives were swabbed for explosive materials. Investigators then opened the computer hard drives and determined there was nothing explosive inside, United Airlines spokeswoman Karen May said.
No one was injured.
