The International Boxing Association has banned the Oakland Police Department from future fights in the "Badge vs. Badge" police boxing series pending an investigation of the causes of an audience brawl Friday night at a Sacramento match.

As KTVU reports, the fight involved several off-duty Oakland police officers and broke out in the audience attending the policemen-only match. Though allegedly no punches were thrown, the audience fight featured pushing, shoving, and chair-throwing.

Friday's starring match at the Sacramento Radisson was between an Oakland police officer and a state prison guard. The audience fracas apparently broke out after someone started trash-talking the OPD. Moral: Don't be dissing the OPD. [KTVU]
