Detroit Metro Airport Security Screening Finds Knife

An airline passenger was arrested after being found with a knife inside the bottom lining of a shoe in his carry-on luggage.

The knife was found, Sunday, during security screening at Detroit Metro Airport in Romulus.

The knife should have been placed in checked luggage.

TSA says finding the knife in the man’s carry-on luggage shows the security screening process is working as it should.

There was no threat to public safety.
