June 13, 2025
Two Chinese scientists accused of smuggling or shipping biological material into the United States without permits will remain in custody in Michigan. They waived their right to a hearing Friday in federal court. Chengxuan Han was arrested Sunday at the Detroit airport. Yunqing Jian was arrested on June 2 and is charged with conspiring with her boyfriend to bring a toxic fungus into the U.S. Both worked at the same University of Michigan laboratory. The university has not been accused of misconduct. Its statement condemns any actions that “seek to cause harm, threaten national security or undermine the university’s critical public mission.”
