FLINT, Mich. (AP) — The FBI says a Canadian man from Tunisia may have chosen to attack a police officer in Flint, Michigan, simply because it has an international airport.

David Gelios, head of the FBI in Detroit, says investigators have found no personal connection between Amor Ftouhi and Flint or Michigan. But Flint’s airport is called Bishop International Airport.

Gelios says Ftouhi “did want to identify an international airport.”

The 49-year-old from Montreal is charged with stabbing Lt. Jeff Neville in the neck Wednesday. The officer is recovering.

The FBI is investigating the attack as a possible act of terrorism but Gelios says the agency has “no information” that the attack was part of a wider terrorism plot.
