Federal prosecutors say a U.S.-trained scientist from Pakistan suspected of being an Al Qaeda operative is faking mental illness to avoid a trial.

Aafia Siddiqui was a global fugitive for five years until she turned up at a police station in Afghanistan over the summer and was wounded in a struggle with U.S. soldiers.

Her mental health has been in question since her arrest.

Psychologists initially concluded she was unfit for trial. But a federal prosecutor told a judge in New York on Thursday that two other psychiatrists say she is manipulating the court by pretending to be ill, The New York Times reported Friday.

A hearing is planned for June 1.

Siddiqui studied at the prestigious Massachusetts Institute of Technology and Brandeis University before returning to Pakistan in 2003.
