An officer for Bishop International Airport in Flint, Michigan, was stabbed Wednesday in what local, state and federal law enforcement authorities were investigating as a terrorist act.
According to witnesses, 52-year-old Canadian Amor Ftouhi, who first entered the United States June 16, allegedly shouted "Allahu akbar" and blamed the United States for deaths in Syria, Iraq and Afghanistan before stabbing Lieutenant Jeff Neville with a large knife.
Multiple senior law enforcement officials with direct knowledge of the investigation told NBC News that the suspect was not in any FBI databases prior to the incident, unlike the majority of suspects in the last several U.S. terror attacks.
The FBI is leading the investigation in coordination with the Bureau of Alcohol, Tobacco, Firearms and Explosives, Michigan State Police and other partners in Flint and Canada.
