Authorities say an airline passenger has been arrested in Michigan after being found with a knife concealed inside the bottom lining of one of his shoes. The Transportation Security Administration says the knife was found Sunday morning during security screening at Detroit Metropolitan Airport.
The TSA says airport police responded, took possession of the knife and arrested the passenger. His name wasn't immediately released. The TSA says the knife should have been placed in checked luggage.
This arrest comes in the wake of word that passengers at some overseas airports that offer U.S.-bound flights will soon be required to power on their electronic devices in order to board their flights. The measure is intended to enhance aviation security at a time of increased threats.
The Transportation Security Administration says it is adding the requirement that passengers coming to the U.S. from some airports must turn on devices such as cellphones before boarding. It says devices that won't power up won't be allowed on planes and those travelers may have to undergo additional screening.
"As the traveling public knows, all electronic devices are screened by security officers," the TSA said in the Sunday release announcing the new steps.
American intelligence officials have been concerned about new al-Qaida efforts to produce a bomb that would go undetected through airport security. There is no indication that such a bomb has been created or that there's a specific threat to the U.S.
