A Maryland teen from Pakistan is in secret U.S. custody, accused of trying to help recruit terrorists for the Pennsylvania woman known as Colleen Jihad Jane LaRose, according to a source close to the family.

The Maryland boy was 15-year-old high school honors student in Ellicott City when he allegedly exchanged emails with Colleen LaRose. Federal prosecutors said that he went online to solicit money for the woman.

Last month, charges were filed against the teenager who is 17 now accusing him for helping Colleen LaRose in her suspected efforts to kill a Swedish cartoonist who offended Muslims.

The two sources identified the suspect, as partner No. 4 in charging documents against LaRose. The name of the suspect and charges against him are under seal, because he is a juvenile.

The teen on July 8, 2009 posted online message which allegedly solicited money to help LaRose plot an attack.

I write this message on behalf of a respected sister, he allegedly wrote in an appeal for urgent funds, according to court documents.

The teen’s family told the Philadelphia Inquirer that they had made a mistake in allowing him be questioned by the FBI at least eight times without a lawyer.

The suspect is in custody in a juvenile detention center northwest of Philadelphia, Associated Press reported. The teen is going through a standard mental health screening and evaluations at a youth facility in Berks County, Pa.

This is a juvenile case and the allegations are extremely serious, so it would be very inappropriate for me to comment on it, Jeffrey M. Lindy, the suspect's court-appointed lawyer told LA Times.

The teen came to the U.S. with his family four years ago and was born in Pakistan.

The teenager had accepted a full scholarship to Johns Hopkins University and had been accepted to attend the University this fall, according to the source.
