American Arrested in Pakistan

(Mingora, Pakistan) From a Daily Times report:

An American national was arrested here under Section 14 of the Foreign Act and a local court has sent her to judicial lock-up, a police official told Daily Times on Wednesday. He said the woman, named Catherine, was arrested in Mingora, about 60 kilometres northeast of Peshawar, in the last week of January, but declined to say where. Police also recovered a marriage certificate from her possession stating that she is married to a resident of Swabi district.

Anybody know what's in Section 14 of the Foreign Act? I can't imagine she was arrested for being married.
