Four people suffered non-life threatening injuries when struck by bullet fragments following Monday’s game between the Athletics and Blue Jays in Oakland. 

The incident occurred after a celebratory postgame fireworks show, at roughly 9:30 p.m. PT Monday night. 

“Officers located three fans struck by bullet fragments from what appears to be celebratory gunfire occurring throughout the city of Oakland,” the Athletics’ organization wrote in a statement. “A fourth victim later walked into a local hospital. All four victims sustained non-life threatening injuries.” 

Oakland Police officers were first notified of a possible shooting victim inside the stadium, leading to the discovery of the victims. 

The investigation into the matter is ongoing, with the Oakland Police offering up to $20,000 for information leading to an arrest. 

A crowd of 24,403 showed up to the Oakland Coliseum to watch the A’s defeat the Blue Jays, 5-1, and the subsequent fireworks display.
