Deputy District Attorney Claudine Ruiz told Judge Esteban Hernandez that the victim was harassed by picketers and got into a verbal encounter with some of them as he left the store.
She said the defendants got into a car and followed the victim's vehicle at speeds up to 80 mph, during which time Thompson, from the passenger seat, allegedly leaned outside and hit the victim's car door with a baseball bat.
"Defendant Thompson swung the bat and hit the victim in (his) face and his eye. He was knocked to the ground by that strike," Ruiz said.
Olvera, the driver of the pursuing car, accelerated and boxed the victim's car in near a freeway onramp, Ruiz said.
The victim got out of his car to ask for the defendants' insurance information, and Thompson hit him in the head, near the eye, with a bat, the prosecutor said.
The victim got off the ground only to be hit in the chest with a bat wielded by Olvera, the prosecutor said.
