The FBI took the lead in an investigation of a shooting by a U.S. Park Police officer in northern Virginia that critically wounded a driver.
The bureau's Washington Field Office said Wednesday it is not releasing any details about the incident, which occurred Friday night near the George Washington Parkway.
Park Police previously said a chase began after a vehicle fled a crash scene. The chase continued several miles south on the parkway from Alexandria into Fairfax County.
Eventually the suspect pulled off the parkway and crashed at an intersection. Park Police said it was unclear whether the suspect was shot before or after he crashed.

The person shot is a white male. The race of the officer who opened fire has not been released.
The FBI said Park Police and Fairfax County Police are cooperating with the investigation.
On Wednesday, Fairfax County Police Chief Edwin Roessler issued a statement saying two Fairfax County police officers responded to the scene but fired no shots. They remain on duty.
Roessler said he sent the officer-involved shooting team to the scene in an abundance of caution.
He said his agency turned over the evidence it has, including in-car videos, to the FBI.
