FLINT, MI -- The Federal Bureau of Investigation says it is too soon to call the knife attack on a police officer at Bishop Airport today an act of terrorism.

"We are aware of reports that the attacker made statements immediately prior to or while attacking the officer, but it is too early to determine the nature of these alleged statements or whether or not this was an act of terrorism," the FBI said in a statement.

A report from an NBC television affiliate claimed a suspect in custody is Canadian-born suspect and shouted "Allahu Akbar" before stabbing officer Jeff Neville multiple times Wednesday, June 21.

The FBI said in its statement that the suspect "is currently being questioned by law enforcement officers."

"Based on the information that we have at this time, we believe this to be an isolated incident. We currently have no specific, credible information that there is a threat to the Flint community."

Today's attack shut down Bishop, which became a massive crime scene after the stabbing, and police officers were posted at Flint City Hall as a precaution.

Neville is in stable condition after initially having been reported in critical condition after the attack.
