WASHINGTON. Homeland Security Secretary Janet Napolitano has sought disciplinary action against people responsible for posting online a manual of security measures at U.S. airports, and has called for a probe into the leak.

 

The 93-page Transportation Security Administration document was posted on a federal procurement Web site last spring and included procedures and technical details for screening operations, metal detectors and explosives detection systems at U.S. airports. It was labeled “Sensitive Security Information” and dated May 28, 2008. Napolitano told a Senate panel that the manual was outdated, but that disciplinary actions have been initiated.
