The FBI said they 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 the alleged statements or whether or not it was an act of terrorism.

"Based on information that we have at this time, we believe this to be an isolated incident," the FBI said in a statement.

Police said a suspect has been taken into custody. The airport released the following statement:

"All passengers are safe and are being evacuated at this time. Please check with your airline for potential cancellations or delays."

The FBI is leading the investigation. The Flint City Hall began operating under heightened security in an abundance of caution after the incident.

"Right now we are still awaiting more information about the situation at Bishop Airport this morning," Flint Mayor Karen Weaver said. "My thoughts and prayers are with all of our law enforcement officers who work to service and protect us each and every day. I want the public to know that several agencies are involved and working to ensure the situation is under control. However, at this time we are taking extra precautions just to be safe."
