Vacaville police Capt. Matt Lydon said when the girl first noticed she was being followed, she walked to a different neighborhood and the driver followed.
"As she walked into the adjacent neighborhood, she saw the Pontiac again," Lydon said, according to KRON-TV. "She hid behind a parked truck on the street as the male went up and down the street a couple of times attempting to get her attention and attempting to have a conversation with her."
The video shows the girl hide behind the truck as the car repeatedly drives by, backs up and stops as the driver tries to engage in a conversation with her.
When the car appears to drive off, the girl takes off running.
Police are hoping someone may be able to help identify the driver and the car.
