Los Angeles ? Two men charged with the severe beating of a San Francisco Giants fan at Dodger Stadium are suspected of assaulting three other Giants fans at the opening-day game, a law enforcement official said Monday.

Detectives believe the other people were approached by suspects Louie Sanchez and Marvin Norwood on the west side of the stadium on March 31.

Eyewitnesses told police they saw Sanchez assault at least one of those unidentified men, said the official, who spoke on condition of anonymity because the investigation is ongoing.

Sanchez has been charged with misdemeanor assault in connection with that incident. Detectives believe both he and Norwood were involved in the other possible assaults, but no charges have been filed.

Sanchez also is accused of misdemeanor battery on a woman at the game. The official said the woman was wearing a Giants shirt and Sanchez threw something at her during the game.

Sanchez and Norwood were charged Friday with felony mayhem and assault charges in the beating of Bryan Stow, a paramedic from Santa Cruz who remains hospitalized with a brain injury.

Sanchez, 29, and Norwood, 30, made their first court appearance Monday.

Their arraignment was continued until Aug. 10.
