The FBI said Wednesday afternoon that it is investigating the stabbing of a police officer at an airport in Flint, Mich., as an "act of terrorism."

Authorities identified the suspect as Amor Ftouhi, a 50-year-old Canadian resident who legally entered the U.S. through Lake Champlain, N.Y., on June 16. He arrived at Bishop International Airport in Michigan on Wednesday.

“We are investigating this incident today … as an act of terrorism,” said David Gelios, the FBI special agent in charge.
