SAN YSIDRO (CNS) - U.S. Customs and Border Protection officials seized nearly 29 pounds of shark fins illegally brought into the country at the San Ysidro Port of Entry, officials confirmed Friday.

A 54-year-old woman entered the border through the pedestrian crossing about 10:15 a.m. on Wednesday.

She was asked to place her belongings through an X-ray machine. An agricultural specialist noticed the illegal shark fins on two of the woman's bags, U.S. Customs and Border Protection spokesperson Angelica De Cima said.

The woman, who is a Mexican citizen, was cited for violating the Lacey Act, a federal fish and wildlife trafficking law. Her visa was canceled and she was returned to Mexico, De Cima said.
