A Russian scientist at Harvard University was freed on bail by a federal judge after spending four months in detention for failing to declare biological material she brought into the US for research.

After winning release Thursday, Kseniia Petrova is scheduled to reappear in court on June 18 for a hearing over whether the government will proceed with a criminal charge for smuggling, which carries a maximum sentence of 20 years in prison and a $250,000 fine.
