US - Muslim arrested in airport knife scare

The AP reports.

ROMULUS, Mich. - A man with a one-way ticket to Yemen attempted to board a plane with a knife hidden in a book, authorities said.

Mohammed Ghanem, 21, of Hamtramck, was jailed Saturday on $500,000 after being arraigned on a charge of possessing a weapon in the sterile area of an airport.

Ghanem was arrested Thursday at Detroit Metropolitan Airport after Transportation Security Administration officers detected the knife "artfully concealed" in the book, airport spokesman Michael Conway said.

Someone had carved out the inside of the book and placed the knife inside it, said Ghanem's attorney, Nabih Ayad.

Does that mean he made it past the metal detectors? If so, how did they discover the knife? Was he profiled and searched more carefully? Or did someone in airport security get suspicious of his one way ticket?
