A Chantilly woman was sentenced to five years in prison for selling counterfeit computer networking equipment, laundering money and fraudulently obtaining U.S. citizenship, authorities said Friday.

Chun-Yu Zhao, 43, along with family members and other co-conspirators in China illegally imported and sold shipments of counterfeit Cisco-branded products, authorities said.

She also obtained U.S. citizenship by lying on her citizenship application, according to authorities.

Zhao was stripped of her citizenship and ordered to pay $2.7 million in restitution, a $17,500 fine, and forfeit millions of dollars in homes, cars, and cash to the United States, according to authorities.

Zhao has been in federal custody since her arrest in July 2010, authorities said. She was convicted of 16 counts, all felonies, in May.
