Detroit—U.S. authorities apprehended a Chinese researcher, Chengxuan Han, at Detroit Metropolitan Airport on Sunday, accusing her of smuggling biological material into the country. This marks the second such incident in recent days,officials said monday.
Han, a doctoral student at the Huazhong University of Science and Technology in Wuhan, allegedly sent four concealed shipments from China to staff at a University of Michigan laboratory as September, according to an FBI criminal complaint. She planned to spend a year there for a project. Federal agents allege Han made false statements about the shipments upon her arrival from Shanghai.
The biological material, related to roundworms, requires a government permit, the complaint states. Shipments were sometimes hidden within books.
Michael shapira, a biologist at the University of California, Berkeley, reviewed the court filing.”It doesn’t strike me as something that is hazardous in any way. But there are rules to ship biological material,” Shapira said.
Authorities also allege Han deleted her electronic deviceS contents three days before arriving in Detroit, stating she wanted to “start fresh,” according to the complaint.
Han remains in custody, awaiting a bond hearing Wednesday.
Last week,two other Chinese nationals faced charges related to smuggling a toxic fungus,also allegedly for research at the University of michigan. One suspect, a university researcher, is in custody. The other was denied entry into the U.S. last year and remains at large.
Regarding the previous case,a Chinese Foreign Affairs Ministry spokesperson stated the government requires overseas citizens to abide by local laws and safeguards their legal rights.
The University of Michigan, in a statement last week, said it is cooperating with the examination and condemns actions that threaten national security or undermine its mission.
What’s next
The FBI continues to investigate the smuggling of biological materials and its potential impact on national security. Han’s bond hearing is scheduled for Wednesday.
