The latest attack occurred Sunday, when the victim, a man in his 20s, had a collision with another driver and three other men pinned him down, police said.
The other driver kicked and hit the victim in the head and face while he was on the ground, police Sgt. David Armas said.
“It was just a minor fender bender that just got totally out of hand,” he said.
The victim, whose name was not released, had scrapes and cuts to his face, but his injuries were not life-threatening, Armas said. A woman in the victim’s car who is eight months pregnant was not hurt, but she was examined at a hospital as a precaution, he said.
The four men, all in their 20s, were arrested for investigation of assault with a deadly weapon. They were not immediately identified.
In a statement, Dodgers officials praised stadium security and Los Angeles police for a “quick security response (that) prevented the confrontation from escalating further.”
Security responded within moments, according to the statement issued Monday.
Dodger President Stan Kasten said the organization is committed to providing a safe, family-friendly environment for fans.
The violence came after Giants fan Bryan Stow was beaten last year. Two men have pleaded not guilty to charges including mayhem and assault. Stadium officials beefed up security after that attack.
