Oakland police investigating 'celebratory gunfire' at A's game

The Oakland Police Department is looking into firearm use within the Coliseum following the Oakland Athletics' victory against the Toronto Blue Jays on Monday, the team announced.

After the game's celebratory Independence Day fireworks display, the police were made aware of at least one victim within the ballpark.

"During the preliminary investigation, officers located three fans struck by bullet fragments from what appears to be celebratory gunfire occurring throughout the city of Oakland," the A's said in a statement. "A fourth victim later walked into a local hospital. All four victims sustained non-life-threatening injuries.

"The Oakland Police Department and Crime Stoppers of Oakland are offering a reward up to $20,000 for information leading to an arrest."

The A's beat the visiting Blue Jays 5-1 on Monday, with the league celebrating July 4th.

Earlier in the day, the Chicago White Sox and Major League Baseball opted to continue playing a game at Guaranteed Rate Field, despite a shooting that killed at least six people during an Independence Day parade at nearby Highland Park.
