Overview

• A white sedan struck the vehicle gate around 2:40 a.m., the driver draped an American flag over the damaged gate, shouted, and fled on foot with no injuries reported.
• FBI officials labeled the incident an act of terror and a targeted attack on the building following an early morning briefing.
• The suspect was identified as Donald Henson of Penn Hills, described as a former service member with reported mental health issues; he is not believed to be armed but is considered dangerous.
• A bomb squad was called to inspect the car after investigators noted writing and vulgarity on the vehicle, and agents are reviewing other potential evidence.
• The FBI said Henson visited the office weeks earlier with an incoherent complaint, and authorities urged the public to avoid approaching him and to call 911 or the FBI tip line with information.
