Four baseball fans were injured by bullet fragments from outside the Coliseum while attending a post-game July 4 fireworks show, according to Oakland Police and the Athletics.

None of the injuries were life-threatening. Police initially were notified of a possible shooting victim inside the ballpark and officers located three fans struck by bullet fragments authorities say appeared to be from celebratory gunfire in Oakland.

“The Oakland Police Department (OPD) is investigating firearm-related injuries that occurred on July 4, 2022, after 9:30 p.m., in the 7000 block of Coliseum Way,” police and the A’s said in a joint statement.

Police initially were notified of a possible shooting victim inside the ballpark and officers located three fans struck by bullet fragments “from what appears to be celebratory gunfire occurring throughout the city of Oakland,” the statement said. An additional victim walked into a hospital, the Associated Press reported.
