A Russian-born scientist at Harvard University accused of smuggling frog embryos into the United States was indicted on Wednesday on additional charges nearly two weeks after her lawyers secured her release from U.

The indictment Wednesday formalizes charges Kseniia Petrova, 31, has been facing since her detainment in February at Logan Airport in Boston.

A Harvard University Medical School researcher could end up in prison for decades after being indicted on charges related to allegedly attempting to sneak frozen frog embryos into the United States.
