German authorities say that the 15-year-old who stabbed a police officer is under suspicion of also supporting a terror organization, Associated Press reports.

The suspect, who has only been identified as Safia S., attacked an officer with a kitchen knife at the Hannover train station in February. She is already being charged with attempted murder and serious bodily harm.

Prosecutors believed that she "adopted (ISIS's) radical-jihadist ideology" last November and has since been in touch with terrorists in Syria.
