Calling him to be innocent, Rana's aunt Suraiya Bano said that he was upset by the cartoon of Prophet Mohammad published in a Danish newspaper but he could never be involved in terrorists activities.
"He was a very pious person.He had told us that he had protested before the media against the Danish cartoonist. This is why the Americans are deliberately using this to malign him," she said.
Earlier Rana's brother, Abbas Rana had also come up in the defence of his brother calling the allegations against him as baseless.
Rana was arrested with David Coleman Headley on Oct 3 by the FBI.
Mumbai police are tracing Headley and Rana's link to the Mumbai terror attacks.
