Some Arabic flashcards are at the center of a lawsuit against the FBI, police and the Transportation Security Administration.

The Associated Press is reporting that a student is suing the agencies after he was handcuffed at Philadelphia International Airport in August and questioned about his Arabic flash cards.

The AP reported the American Civil Liberties Union filed the lawsuit on Wednesday on behalf of Nick George, 22, of Wyncote, Pa.

It alleges that George, who studies Arabic at Pomona College in California, was detained for four hours and missed his flight to California even after it became apparent he was no threat, the news service reported.
