LOS ANGELES -- Two people suspected of critically injuring a man outside Dodger Stadium are believed to be a mother and son, Los Angeles Police Chief Charlie Beck said Tuesday.
Police declined to discuss what precipitated the fight Friday night, but Beck said detectives were reviewing video that captured the assault in hopes of tracking the pair down.
Police described the mother as being in her 40s or 50s and her son as being between 25 and 30.
The man injured in the fight, who was taken to the hospital in critical condition, was in serious but stable condition Tuesday. Detectives began interviewing him Tuesday for more details about what happened, and they will be speaking to him again, Officer Mike Lopez said.
The fight happened in a stadium parking lot after the Dodgers lost the opening game of the NL Division Series 3-1 to the New York Mets. It began with an argument and quickly escalated into violence, police said.
Beck declined to discuss whether the injured man and the suspects knew each other or whether they were rooting for opposing teams.
Witnesses told the Los Angeles ABC affiliate that the fight took place between Dodgers and Mets fans and the injured party was a Mets fan. They said the man was punched, and then he fell and struck his head.
Beck called the assault very unusual and said stadium security has been significantly enhanced since the 2011 beating that left San Francisco Giants fan Bryan Stow with brain damage.
"Anyone who goes to games now sees uniformed officers inside the venue, as well as outside the venue, particularly for championship games or key rivalries," Beck said. "But it is a big facility, and you can't be everywhere all the time."
Beck urged anyone who saw or recorded the incident to contact police.
Should the Mets return to Los Angeles for a Game 5 on Thursday, Beck said police will have a strong presence at the stadium, "particularly with the tensions between the two teams right now and the fans, obviously."
"There's been a significant amount of rivalry here -- a lot at stake," he said.
Police said fan expulsions were higher than usual at Friday's game, though they didn't have specific figures.
Dodger spokesman Steve Brener said Tuesday that the team had no comment.
Security at Dodger Stadium came under national scrutiny after the attack in the parking lot on Opening Day 2011 left Stow with brain damage. Two men -- Marvin Norwood and Louie Sanchez -- pleaded guilty in that beating and went to prison.
Stow sued the Dodgers and their former owner, Frank McCourt, blaming them for the attack because of insufficient security and lighting. A jury faulted the team, along with Sanchez and Norwood, and awarded Stow nearly $18 million after a six-week trial in 2014.
