ST. LOUIS (AP) — A US Airways flight from New York to Phoenix has been diverted to St. Louis after three passengers acted suspiciously.

A Transportation Security Administration statement says US Airways flight 457 landed at Lambert Airport shortly before 8 a.m. Tuesday due to the suspicious behavior of three passengers. Agency spokeswoman Sarah Horowitz would not elaborate.

Lambert spokesman Jeff Lea says the plane landed without incident. The TSA has not said if anyone was taken into custody. Federal authorities are investigating.

The incident comes amid heightened air travel security concerns around the 10th anniversary of the Sept. 11, 2001, terrorist attacks.

On Sunday, a GoJet Airlines flight from St. Louis to Washington returned to the gate at Lambert after crew became concerned when they found paper towels stuffed in a toilet.
