The terminal was evacuated at around 5:30 a.m. Saturday after the man approached security in the airport's C concourse, Port Authority of New York and New Jersey spokesman John Kelly said.

It wasn't clear if the man made a threat, but security officials said he "was just acting crazy," Kelly said. The man's name was not released.

The device in the man's bag was a few batteries and wires, but was not dangerous, police said.

Police later reopened the main terminal, and passengers began re-entering shortly before 9 a.m.http://news.yahoo.com/s/ap/20090801/...dia_evacuation

A wasted three and a half hours when it was already determined the man is crazy. Oh, I forgot, they needed to page a psychiatrist (to make that medical determination) and order a couch from Jennifer Convertibles.
