A California woman was arrested Saturday for trying to smuggle $100,000 in cash into Mexico in a laundry detergent box, officials said.

Customs and Border Protection officers at the Dennis DeConcini Port in Nogales were conducting outbound inspections and selected a Honda sedan, driven by Blanca Gabriela Medina, 29, of El Monte, Calif., for an additional inspection.

Officers searched the vehicle and found 10 packages of cash hidden in a box of Gain detergent, the agency said in a news release.

The vehicle and cash were processed for seizure. Medina was turned over to U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.
