Reuters reports that a man has been indicted for stabbing a police officer in a Michigan airport last year on a terrorism charge. Amor Ftouhi, 50, a Canadian citizen, has allegedly committed “an act of terrorism transcending national boundaries.” Ftouhi crossed Canada’s border to attempt to kill government officials in the U.S. according to the indictment.

Ftouhi has a court-appointed attorney who has not responded to requests for comment yet.

He is originally from Tunisia and is a dual citizen. Ftouhi was originally charged last year with violence at an international airport after allegedly stabbing an officer at the Bishop International Airport in Flint, Michigan. Officer Jeff Neville suffered injuries to his neck during the attack.

This newest charge of terrorism supersedes the first and carries a potential life sentence if convicted.

Ftouhi allegedly researched American gun laws in Montreal before finding the closest state where he could purchase a firearm. He withdrew bank funds to purchase a gun and drove to the U.S. at the Champlain, New York port five days before the attack.

Around June 18, 2017 he went to a gun show in Michigan and purchased a knife because he was unable to get a gun there.

On June 21, 2017 he attacked Neville while shouting “Allahu Akbar (God is greatest).” He also referenced murders in Syria, Iraq and Afghanistan.

Ftouhi told authorities after his arrest that he was a “soldier of Allah” and subscribed to the ideology of al-Qaeda and Usama bin Laden. He will be arraigned at a later date.
