Authorities are searching for a Penn Hills man accused of ramming the entrance gates of the FBI's Pittsburgh Field Office early this morning.
They say Donald Henson drove a white sedan into the gates around 2:40 a.m. Henson threw an American flag over the gate and the car had a message written on the windows.
He then fled the scene on foot.
A bomb squad was called to check the vehicle before it is moved.
The FBI considers the incident a “targeted attack against the FBI.”
No one was injured during the incident.
There's no indication Henson is armed, but he is believed to have a history of mental health issues.
If you see Henson, you’re asked to call 911 or call the FBI at 1-800-CALL-FBI.
