An American Airlines flight headed from San Francisco to JFK had to make an emergency landing in Kansas City yesterday after a camera disguised as a flashdrive was discovered taped to a wall inside a lavatory.

It's unclear who discovered the camera, which authorities treated as a potential bomb threat. Passengers were told at the time that there was a problem with the air circulation system. When the Boeing 767 landed, more than 200 people were removed and kept in an unused terminal for several hours while authorities searched the plane.

No arrests have been made, but security officials — including the Kansas City FBI — are investigating who placed the camera in the bathroom.
