The FBI is investigating the shooting of an Air Force helicopter in northern Virginia that injured a crew member Monday.

The UH-1N Huey from the 1st Helicopter Squadron at Joint Base Andrews in Washington was flying a training mission over Middleburg, Virginia, when it was shot from the ground nearby, according to the New York Times.

“Initial findings are that the helicopter was struck by a bullet resulting in a minor injury to an aircrew member and damage to the aircraft,” a Joint Base Andrews spokesperson told Coffee or Die over email.

The helicopter was forced to make an emergency landing at Virginia’s Manassas Regional Airport. The injured crew member was taken to a local hospital, treated, and released, according to officials.

The FBI and US Air Force Office of Special Investigations are investigating the incident together. The FBI is asking the public to call in any information connected with the incident.

The 1st Helicopter Squadron supports distinguished visitor flights, medical evacuations, and search and rescue assistance in the area. Its primary mission is to transport key government officials during national emergencies.
