The victim, a 20-year-old Concord resident, called police at about 11:15 a.m. and reported that she had been walking in the 2000 block of Sunshine Drive when a white car approached her.
The car was driving the wrong way when it pulled up to her, she told police.
The victim told investigators a man sitting in the rear passenger seat opened the door and instructed her to get in the car, Gartner said. When she refused, the man allegedly grabbed her wrist and arm and tired to pull her toward the car.
The victim allegedly punched the man once in the side of his face and he let go of her, then got back in the car and the suspects sped away, Gartner said.
The car was described as a white, four-door Honda Civic with a black rear bumper and a red temporary registration sticker on the rear window.
The driver was described only as a Hispanic man.
The passenger was also described as a Hispanic man and was said to be between 20 and 30 years old, about 5 feet 7 inches tall and weighed about 150 to 165 pounds.
He had brown hair in a buzz cut and was wearing a red shirt, blue jean shorts and white Adidas tennis shoes with red laces, the victim told police.
Police searched the area and issued a countywide alert to neighboring law enforcement agencies, but found no trace of the vehicle or the suspects.
There were no witnesses and no motive has been established, Gartner said.
