CHICAGO, April 14 (UPI) -- The Chicago Department of Aviation is refusing to comment on a report of a security breach at O'Hare International Airport involving sensitive information.

In an article Monday, The Chicago Sun-Times said uniforms belonging to officers of the Transportation Security Administration were left out in the open at an O'Hare checkpoint last month along with sensitive security information and a cash box.

A Department of Aviation report obtained by the newspaper also revealed two TSA radios with access to a secure channel were found unsecured at Checkpoint 8 and break-room doors at two checkpoints were unlocked.

TSA spokeswoman Elio Montenegro has confirmed the report and its contents are genuine.

Montenegro said all of the items described were in the area where passengers are permitted after going through security checkpoints.

In 2006, WMAQ-TV, Chicago, reported that in a five-year-period, TSA employees at O'Hare lost 189 identification badges, the most of any U.S. airport, and 188 uniforms.
