Customs officials say a man arriving at Washington Dulles International Airport from Guatemala was carrying more 11 pounds of heroin hidden inside juice boxes.

An Immigration and Customs Enforcement agent said in a sworn statement that the heroin has a value of up to $600,000 on the streets of Washington.

Court documents state Emmanuel Rios was traveling on a U.S. passport when he flew from Guatemala to Dulles on a TACA Airline flight December 13 and was selected for a routine inspection by a border patrol officer.

Inside Rios' luggage, the officer found 24 juice boxes bundled together, but could feel that there wasn't juice inside. Instead, court documents state, a light-brown powdery substance wrapped in a condom was inside.

Rios' attorney, Douglas Steinberg, declined to comment.
