The Detroit Free Press and the Windsor Star say a complaint was filed Tuesday in Detroit federal court against a 51-year-old woman.
The complaint says border agents detained Moura El-Asmar and her 16-year-old daughter at the Detroit-Windsor Tunnel on their way to Detroit Metropolitan Airport for a flight to visit relatives in Lebanon.
It's alleged that agents found $15,300 in El-Asmar's purse, and that a pat down found "a bulky mass" in her bra that led to the pair's hidden cash.
The Windsor-area woman is charged with cash smuggling and lying to a federal agent.
Her daughter isn't charged.
