## Key points

- Prosecutors say continuing Petrova’s case would cost too much.
- She was accused of bringing undeclared frog embryos into the US.
- The case followed her detention after returning from France.

## Summary

The U.S. Justice Department has asked a court to drop its case against Kseniia Petrova, a Russian researcher at Harvard Medical School accused of illegally bringing frog embryos into the country. Prosecutors said the cost of continuing the case outweighs the public interest in resolving it.

Petrova was detained in February after returning from France with undeclared embryos in her luggage. She said she did not know they had to be declared; she faced smuggling charges carrying up to 20 years in prison, as well as charges of giving false testimony and concealing facts. The request to end the case followed defence demands for details about her detention and information about others who had brought in similar materials without declaring them.
