Celebratory Gunfire Wounds 4 After Oakland Coliseum Fireworks Show

OAKLAND, CA — Four people, including three Oakland A's fans, were wounded by celebratory gunfire following a postgame fireworks show at the Oakland Coliseum.

Police officers were called for a possible shooting victim inside the ballpark around 9:30 p.m. Monday, Oakland police said. Officers found three fans struck by bullet fragments in what appeared to be celebratory gunfire happening throughout the city.

A fourth person suffering from a bullet fragment later walked into a hospital, police said. All four are expected to survive their injuries.

An 11-year-old boy was among the victims, along with two women and a man, Bay Area News Group reported. Authorities believe the bullets were fired from outside the stadium.

Authorities are offering a reward up to $20,000 for information leading to an arrest.

Police said they're working with the team's security staff to ensure fans are safe at future A’s games at the Coliseum.

The A's (27-55), who are 5th in the AL West, defeated the Toronto Blue Jays (44-37) on Monday night 5-1.
