CHICAGO (AP) — Defense attorneys are seeking no more than a nine-year prison term for a Chicago businessman convicted of supporting a terrorist group that staged attacks in 2008 on Mumbai, India.

A defense filing before Tahawwur Rana’s (tuh-HOW'-ur RAH'-nahz) sentencing Thursday describes him as charitable and kind-hearted. It says he was duped into participation by a manipulative childhood friend, David Coleman Headley.

Prosecutors are asking a federal judge in Chicago to impose the maximum 30-year sentence.

Jurors in 2011 convicted Rana of supporting a never-carried-out plot to attack a Danish newspaper that printed cartoons of the Prophet Muhammad and for supporting the group that attacked Mumbai, killing more than 160 people.
