Police Wednesday are still searching for a mother and son in a brutal beating of a reputed Mets fan outside of Dodger Stadium Friday night, according to multiple reports.

“Embarrassed to be a Dodger fan as my Mets fan friend is in the hospital missing a piece of his skull after being hit by a lowlife,” the Daily News reports a friend of the Mets fan posted on Twitter.

Los Angeles Police Chief Charlie Beck said detectives were reviewing video that captured the assault in hopes of tracking the pair down, the Associated Press reported. Authorities haven't said what prompted the attack or named the victim, but police described the mother as being in her 40s or 50s, and her son as being between 25 and 30, according to the AP.

The victim was reported to be in serious but stable condition Tuesday, and officers have begun interviewing him, the AP reported.

The fight happened in the Dodger Stadium lot after the New York Mets beat the Dodgers 3-1 in the opening game of the National League Division Series. Authorities haven't said if the fan and the mother-son duo knew each other, or whether the fight was over the game.

Beck told the AP that should the Mets return to Los Angeles for a Game 5 on Thursday, police will have a strong presence at the stadium, "particularly with the tensions between the two teams right now."

Those tensions — aside from the usual sports rivalries — were heightened Saturday after a takeout slide by the Dodgers' Chase Utley’s broke Mets shortstop Ruben Tejada’s right leg.

TV station NBC4 in Los Angeles quoted an unidentified friend of the reputed Mets fan saying he is from Bakersfield, Calif.

The Dodgers organization has made no comment on the incident.
