A U.S. Border Patrol agent fatally shot a woman in a South Bay neighborhood Friday afternoon.
Agents involved in the shooting were not in uniform but in plain clothes, the Chula Vista Police Department said.
An investigation will be conducted by the FBI and Chula Vista Police Department in cooperation with the Border Patrol and the United States Office of Inspector General.
The gunfire in the 600 block of Moss Street in Chula Vista was reported about 1 p.m., according to police and federal officials. The woman died at the scene.
The woman apparently was in a green Honda Accord near Woodlawn Avenue when she was shot, NBC 7 San Diego reported.
Officials said agents were serving a felony warrant when a deputy was hit by the car and carried several yards.
"The suspect was armed with a vehicle, and literally ran our agent down," CBP Chief Patrol Agent Rodney Scott told the news station.
The condition of the agent hit by the car is unknown at this time.
It is not known if agents from the Imperial Beach Border Patrol station were involved in the incident.
