Amor Ftouhi has an allegedly deep-rooted hatred for America.

And on Wednesday, that rage exploded in an airport in Flint, Mich., when the Montreal father of three stabbed a police officer in the neck with a combat knife.

The 50-year-old reportedly shouted “Allahu akbar,” the Arabic phrase for “God is great,” before striking the officer.

FBI Special Agent David Gelios said that the feds believe Ftouhi was a “lone wolf” and not part of a larger conspiracy. He added the sometime truck driver has been “cooperative.”

“We interviewed the subject for a good period of time ... Suffice to say, he has a hatred for the United States and a variety of other things that motivated him to come to the airport ... to commit this act of violence,” Gelios told the Detroit News.

The Montrealer also mentioned U.S. military operations in Syria and Iraq as his motivation for attacking the cop.

The dual Tunisian-Canadian citizen speaks little English but is fluent in French and Arabic. In court, he struggled to understand some instructions.

Ftouhi’s mother, three sisters and two brothers live in Tunisia while another sister resides in Switzerland.

In court, he claimed he had no mental or physical health problems nor did he have drug or alcohol issues.

The FBI said Ftouhi asked cops: “Why did you not kill me?”

Investigators say he used an Amazon Jungle Survival Knife.

Cops in Montreal raided Ftouhi’s east-end apartment and were bringing in three people for questioning.

The victim - Officer Jeff Neville - has had his condition upgraded to stable.

The portrait being painted of Ftouhi as a dangerous radical is at odds with the man his landlord and neighbours have come to know.

“I’m very surprised,” landlord Luciano Piazza told CBC News.

“He’s a good person, very quiet. I’ve never had any problems with him,” Piazza said, adding Ftouhi has lived in the building for five years. ”They’re really good people.”

Friend Kamel Yahyaoui told The Canadian Press Ftouhi wouldn’t think of “hurting a fly.”

“He’s a socially positive person,” Yahyaoui said. “He’s looking for a good life for him and his family. That’s all.”

Muslim neighbours were also worried that Ftouhi’s alleged actions could put them in harm’s way.

“Stupid acts like that put our lives in danger,” Ichrak Laib told Radio-Canada.

Meanwhile, it’s believed Ftouhi entered the U.S. June 16 at Lake Champlain, N.Y., before making his way to Flint.

If convicted he faces up to 20 years in a U.S. prison.
