A scientist and research associate at Harvard University accused of smuggling frog embryos into the United States was indicted Wednesday on additional charges, nearly two weeks after she was released from custody.

Russian-born Kseniia Petrova, 30, was indicted by a federal grand jury in Boston on one count of concealment of a material fact, one count of false statement, and one count of smuggling goods into the United States.
