The FBI confirmed Wednesday afternoon a man who stabbed a police officer at Bishop International Airport in Flint, Mich., earlier in the day has been taken into custody.

Federal officials said the affected officer is in stable condition following the incident and the unnamed suspect is currently being questioned by law enforcement officers.

Local and federal officials are investigating the person's motive for the attack. Witnesses told local TV networks the person had yelled "Allahu Akbar" -- a phrase that is often uttered by Islamic State affiliates prior to violence that means "Allah is the greatest" -- before attacking the officer.

"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.

The FBI believes the attack was an isolated incident and there is no pending attack on the greater Flint community.

"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," the statement read.
