US authorities seek leniency for Bangladeshi ISIS cooperator

US authorities are seeking leniency for a Bangladeshi immigrant who joined ISIS in Syria before fleeing home and giving the FBI intelligence about terror threats.

The New York City man, identified only as “John Doe” for security reasons, appeared at a sentencing on Wednesday in federal court.

Prosecutors have described how the man fell under the influence of ISIS recruiters and traveled to Syria in 2014. They say the group gave him a support role until he became disillusioned and secretly reached out to the FBI.

The 29-year-old man wept as he apologized to the court for joining the militant group. He called it “the greatest mistake of my life.”

A judge put off imposing a sentence until Thursday.
