Suspicious items prompt TSA warning
WASHINGTON – Airport security officers around the nation have been alerted by federal officials to look out for terrorists practicing to carry explosive components onto aircraft, based on four curious seizures at airports since last September.
The unclassified alert was distributed on July 20 by the Transportation Security Administration to federal air marshals, its own transportation security officers and other law enforcement agencies.
The seizures at airports in San Diego, Milwaukee, Houston and Baltimore included “wires, switches, pipes or tubes, cell phone components and dense clay-like substances,” including block cheese, the bulletin said. “The unusual nature and increase in number of these improvised items raise concern.”
Security officers were urged to keep an eye out for “ordinary items that look like improvised explosive device components.”
The 13-paragraph bulletin was posted on the Internet by NBC Nightly News, which first reported the story.
A federal official familiar with the document confirmed the authenticity of the NBC posting.
“There is no credible, specific threat here,” TSA spokeswoman Ellen Howe said Tuesday. “Don’t panic. We do these things all the time.”
Homeland Security spokesman Russ Knocke described the notice as the latest copy of a routine informational bulletin for TSA workers, airport employees and law enforcement officials.
A statement posted late Tuesday by the TSA on its Web site confirmed that “a routine TSA intelligence bulletin relating to suspicious incidents at U.S. airports” had leaked to news organizations. The statement added, “During the past six months TSA has produced more than 90 unclassified bulletins of this nature on a wide variety of security-related subjects.”
The bulletin said the passengers carrying the suspicious items seized since September included men and women and that initial investigation had not linked them with criminal or terrorist organizations. But it added that most of their explanations for carrying the items were suspicious and some were still under investigation.
