PHILADELPHIA  - A Pakistani-born teenager accused of helping a terror cell based in Ireland will plead guilty to a US terrorism charge, according to court papers filed Monday.

According to the USA Today, Mohammad Hassan Khalid became a rare juvenile suspect held in FBI custody after his arrest last summer, when he was a 17-year-old high school student in Ellicott City, Md. Khalid had met a Pennsylvania woman who called herself Jihad Jane in an online chat room when he was 15 and had agreed to help her seek money and recruits to wage a Muslim holy war in Europe and South Asia, authorities said.

The woman, Colleen LaRose, admitted last March that she had plotted to kill a Swedish artist who had offended Muslims. LaRose, 48, faces a sentence of life in prison. She is not just a homegrown terrorist but a rare female one.

Khalid was arrested in July. He first appeared in open court in October, after he turned 18 and was indicted on a charge of aiding terrorism. He has pleaded not guilty to the charge, which carries a maximum 15-year prison sentence.

Defence lawyer Jeffrey Lindy declined to comment on the scheduled April 2 change-of-plea hearing. He previously said that he believes LaRose helped the FBI build its case against his client.

Assistant US Attorney Jennifer Williams did not immediately return a message late Monday from an America news agency.

Khalid and his family are legal immigrants from Pakistan. He could be deported if convicted.

Teachers at Mount Hebron High School said they remember Khalid, a 2011 graduate, for his strong work ethic.

Khalid had been offered a full scholarship to prestigious Johns Hopkins University. But in a secret life online, he pledged to forward money to LaRose for her to pass on to the jihadists, or holy warriors, and hid a passport she sent him, authorities said.

Khalid was indicted along with Ali Charaf Damache, an Irish citizen from Algeria who married another American woman, Jamie Paulin-Ramirez, of Colorado, after she moved to Waterford, Ireland, to meet him. Paulin-Ramirez, 33, pleaded guilty last year to providing material support to terrorists, the charge now facing Khalid.
