The latest attack occurred Sunday, when the victim, a man in his 20s, had a collision with another driver. 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.
The four men were arrested for investigation of assault with a deadly weapon. They were identified late Monday as Arthur Morales, 20; Alan Trujillo, 29; Alejandro Briceno, 29; and Ulises Briceno, 26. The men have been released after posting bail, $30,000 each.
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.
In a statement, Dodgers officials praised stadium security and Los Angeles police for a “quick security response (that) prevented the confrontation from escalating further.”
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. Stow’s family has filed a lawsuit against the team and previous owner Frank McCourt, claiming security cutbacks were partially to blame for the attack.
The Dodgers were sold earlier this year to an ownership group that includes NBA legend Earvin “Magic” Johnson.
Dodgers security staff and uniformed off-duty Los Angeles police officers were at the stadium Sunday and responded quickly.
Cmdr. Andrew Smith said the officer who detained the suspects was an off-duty LAPD officer who was working in uniform for the Dodgers.
The beating Sunday occurred after the Dodgers’ 6-5 win over St. Louis.
