The FBI says a driver rammed a vehicle into the front gate of its Atlanta office but his motives were not immediately known.
The crash happened shortly after noon local time.
Pete Ellis, the assistant special agent in charge of the United States agency’s Atlanta office, told reporters the man tried to follow another vehicle through the gate and onto the FBI campus in suburban Chamblee, Georgia, but security precautions prevented him from entering. Several special agents who were passing by took the man into custody and no-one was injured, Ellis said.
The man, who was not associated with the FBI facility, was taken to an Atlanta hospital for evaluation, Ellis said.
Law enforcement officials are looking into both state and federal charges.
