A driver crashed a vehicle into a security gate at the FBI facility in Pittsburgh early Wednesday morning. After the collision, the person removed an American flag from the back seat and draped it over the gate before departing, according to officials.

The incident occurred around 2:40 a.m., as reported by the FBI, and law enforcement is currently in pursuit of the suspect. Bomb squad teams and investigators are on the location.

According to an online statement from the agency, “This incident is considered a targeted attack against the FBI.” Fortunately, no FBI staff members were harmed.

Christopher Giordano, the assistant special agent in charge at the FBI’s Pittsburgh division, informed reporters that the vehicle had some sort of message written on one of its side windows.

Giordano said the FBI was familiar with the man.

“He did come here to the FBI field office a few weeks ago to make a complaint that didn’t make a whole lot of sense,” Giordano said.
