US reports the arrest of another Chinese scientist with no permit to send biological material

Chinese doctoral student Chengxuan Han entered the United States through Detroit Metropolitan Airport on June 8, 2025, holding a J1 visa, and was detained on suspicion of smuggling biological materials.
Han sent four packages with concealed biological material related to roundworms from Wuhan, China, to a University of Michigan laboratory in 2024 and 2025.
Customs officers found that Han’s electronic device had been wiped clean, and during questioning, she acknowledged dispatching the packages and making false statements throughout the inspection.
U.S. Attorney Jerome Gorgon described the case as indicative of a concerning trend that poses risks to national security, while FBI Special Agent Cheyvoryea Gibson emphasized that it represents a serious threat to public safety.
Han remains in custody with a bond hearing set for June 11, 2025, as the FBI, CBP, and ICE continue investigating related smuggling cases involving other Chinese nationals.
