Harvard researcher detained in February for failing to declare frog embryo samples says she didn’t lie to government
- Kseniia Petrova, a 30-year-old Harvard Medical School researcher, has been detained by ICE in Louisiana since February for failing to declare non-hazardous frog embryo samples she carried for cancer research.
- Her detention resulted after she did not correct inaccuracies in a customs inspection statement, while U.S. Officials allege she lied and deliberately evaded law enforcement.
- Petrova accepts full responsibility for the incomplete declaration of the samples and acknowledges that she should have been more familiar with customs documentation, but maintains that immigration officials misunderstood her statements.
- Petrova stated, "I never provided false information to any government official" and questions why officials consider her a danger and flight risk despite her research focus.
- After over 10 weeks in detention, Petrova will appear in federal court in Vermont this month to challenge her detention, while her attorney warns deportation could lead to her immediate arrest in Russia for her prior opposition to the Ukraine invasion.
