BOSTON (AP) — A woman accused of paying $400,000 to get her son into the University of California, Los Angeles, as a fake soccer recruit has become the 52nd person charged in a sweeping college admissions bribery scheme, according to an indictment unsealed Tuesday.

Xiaoning Sui, 48, of Surrey, British Columbia, was charged with a single count of conspiracy and fraud in the indictment unsealed in Boston’s federal court. Authorities say she was arrested in Spain on Monday night and was being held there while authorities seek to extradite her to the United States.

Sui is the first person to be charged since June, when parent Jeffrey Bizzack pleaded guilty to paying $250,000 to get his son into the University of Southern California as a fake athlete. Dozens of others were charged in March when authorities announced the investigation.

It was not immediately clear whether Sui had an attorney to speak for her.

Prosecutors say Sui paid $400,000 to a sham charity operated by admissions consultant William “Rick” Singer as part of a scheme to have her son admitted to UCLA as a fake soccer recruit. Sui is accused of providing Singer her son’s transcript and photos of him playing tennis.

Singer worked with Laura Janke, a former assistant soccer coach at USC, to fabricate an athletic profile depicting Sui’s son as a top player on two private soccer clubs in Canada, prosecutors said. Both Singer and Janke have pleaded guilty.

Sui’s son was admitted to UCLA as a soccer player in November 2018, authorities say, and was awarded a 25% scholarship.

The case was outlined in a March indictment against former UCLA soccer coach Jorge Salcedo that didn’t identify Sui by name.
