A California couple, Silvia Zhang and Guojun Xuan, is arrested and charged with child abuse offenses following an investigation into a surrogacy arrangement involving multiple children, authorities say. The pair are taken into custody at their home in Arcadia, according to reports.

Police and prosecutors describe the case as involving at least 21 children, with some outlets reporting higher numbers based on the scope of the investigation. Authorities say the children were removed from the couple’s home, and that the allegations relate to conduct toward minors in the context of surrogacy. The Guardian reports children ranging from very young infants to older minors were taken.

Different outlets focus on the same core allegations but vary slightly in the reported totals and framing. Several sources state the charges include conspiracy to commit child abuse, citing the Los Angeles County Sheriff’s Department. The Oregonian and others quote prosecutors characterizing the case as unusually severe or unprecedented.

Overall, the coverage aligns on the arrest, the names of the couple, the surrogacy-related investigation, and the child abuse charges, while differing on the exact number of children referenced in the investigation.
