Police say they have located the man who allegedly rammed his car into the gates of the FBI field office in Pittsburgh in what the bureau called a "targeted attack."

Donald Henson, of Penn Hills, Pennsylvania, was taken into custody on Sept. 17 hours after allegedly driving a white sedan into the gates, throwing an American flag onto the damaged gates and then fleeing the scene on foot, according to the FBI. No law enforcement personnel were injured during the incident, which FBI Special Agent in Charge Christopher Giordano told reporters is considered a federal offense.

"We look at this as an act of terror against the FBI," Giordano said. "This was a targeted attack on this building."

Giordano said Henson, who officials believe has a military background and a history of mental health issues, previously came to the field office to make a complaint that "didn't make a whole lot of sense" and resulted in no federal charges being filed.

He shared a photograph of Henson and urged members of the public to contact police if they had any contact with him.

Bradford Arick, a spokesperson for the FBI Pittsburgh, confirmed that Henson had been "apprehended," but did not immediately respond to questions from USA TODAY about what charges he will face and where he is being held.
