FBI agents raided a Michigan home Thursday night in an operation described as a matter of national security.
The operation took place in Dearborn and the scene was cleared before midnight, Fox 2 reported.
The operation stemmed from an incident that occurred out of state, the Detroit Free Press added, reporting that investigators tracked the suspects to the area. Law enforcement officials from multiple regions were on the scene.
"FBI personnel are on scene conducting a law enforcement operation. There is no threat to public safety,” FBI spokesperson Timothy Wiley told the newspaper.
Officials were expected to give more details about the operation sometime Friday.
