PHILADELPHIA -

An 18-year-old man has been indicted on charges he helped the terror suspect dubbed "Jihad Jane" with her plot to kill a Swedish artist.

Federal authorities said they indicted Mohammad Hassan Khalid, a legal immigrant from Pakistan and former high school honors student.

Khalid has been the rare juvenile in federal custody since his July 6 arrest, when he was 17, at his family's home in Ellicott City, Maryland.

The indictment charges that he helped recruit women with passports to further the plot of Colleen LaRose of Pennsburg, Montgomery County, Pennsylvania, and others. He faces up to 15 years, and could be deported, if convicted.

The teen's lawyer, Jeffrey M. Lindy, did not immediately return a call for comment.

Also named in the indictment released Thursday is an Algerian who lived in Ireland and married another suspect in the case, Jamie Paulin-Ramirez of Colorado.
