One man is injured and another is in custody following a shooting on the Blue Ridge Parkway, according to a parkway official.

Chief Ranger Neal Labrie said two men were driving near mile marker 116, near Explore Park, about 10:15 a.m. when a road rage incident resulted in a shooting. Roanoke County police arrived to the scene within about 15 minutes.

"We understand that one presented a weapon an the other responded with shooting," Labrie said.

One man was taken to a hospital for treatment. The man suspected of shooting him is being held at the scene, Labrie said.

The parkway is under the jurisdiction of the National Park Service, and as such, the case falls under federal jurisdiction. Labrie said the FBI is involved as well as the U.S. attorney's office. He said the Blue Ridge Parkway is the lead agency in the investigation at this time.

Authorities have shut down the parkway from Virginia 24 to U.S. 220 while authorities investigate.
