Driver Rams Car Into FBI Building Gate

A Pennsylvania man was apprehended after he drove his car into a metal gate at the FBI building in Pittsburgh early on Wednesday, a ramming that federal law enforcement officials described as intentional.

Donald Henson, of Penn Hills, allegedly drove at a high rate of speed toward the main entrance gate at about 2:40 a.m., FBI Special Agent in Charge Christopher Giordano said during a press briefing.

The FBI confirmed late Wednesday morning that Henson was apprehended "a short time ago."

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

There was "some vulgarity" scrawled on the side of the vehicle, the FBI said. The full details of what was written were not immediately clear, Giordano said, adding there appeared to be a reference to suicide.

Officials said no one was injured in the ramming.

He said the suspect fled the scene and it was believed that he may be dangerous. It was not immediately clear if Henson was armed, the FBI said.

Henson is the registered owner of the vehicle, Giordano said. The FBI compared surveillance video with Henson’s drivers license photo to further identify him, Giordano said, adding that he also had been identified as a former military member. He said Henson may have been experiencing a mental health issue.

After the crash, Henson allegedly exited the car, took an American flag out of the trunk and stuck it on the gate, the FBI said.

Images from the scene captured by ABC News affiliate WTAE appeared to show a white sedan sitting with a door ajar in front of a damaged metal gate near a security booth.

A spokesperson from the Pittsburgh Police Department told ABC News that officers responded to the 3300 block of E. Carson Street for a reported vehicle collision at about 3 a.m. on Wednesday. The vehicle collided with a gate outside of the building, before the driver exited the vehicle and fled the scene, the spokesperson said.

The FBI is leading the ongoing investigation, the police said. The FBI was working with the local U.S. Attorneys Office to draft a complaint against Henson, Giordano said.

Henson had come to the FBI Pittsburgh office within the last few weeks to make a complaint, Giordano said, adding it "didn't make a whole lot of sense."

"We contacted him and let him know that there was no federal crime we were able to charge," he said.
