An unattended "vibrating bag" at O'Hare International Airport this morning caused a brief scare but was determined harmless.

The package was reported to police around 8 a.m., which prompted a response from the Chicago Police Department's Bomb and Arson Unit, a unit sergeant said.

"It was someone's property," Chicago police Officer Marcel Bright said. "There was nothing dangerous in it. Someone walked away and forgot it."

Authorities wouldn't say what was in the bag, but police did not have to destroy it, Bright said. The area was declared safe at 9 a.m.

I'm just going to say it...if they won't come out and say what was in the bag, I have a pretty good feeling that it was a vibrator.
