Federal agents have arrested a Chinese national in Honolulu for illegal importation of counterfeit weight-loss medication.

A U.S. Immigration and Customs Enforcement statement issued Thursday in Denver says 30-year-old Sengyang Zhou of Kunming had traveled from China to Hawaii intending to meet with people interested in distributing his pills in the U.S.

The statement said the arrest came Tuesday, the same day that an alleged accomplice, 60-year-old Qung Ming Hu, was arrested in Plano, Texas.

The two have been charged with a number of crimes, including the introduction and delivery into interstate commerce of unapproved new drugs.

Zhou is being held without bond. Hu was released on bond, agreeing to appear April 7 in Denver to face the charges against her.
