Here's what happened:

Police reports confirm the awaiting arrest warrant for Broner was due to his reaction to a boxing fan, David Gonzalez alleging the boxer struck him in the right hand, thus knocking his cell phone—which the victim used to record Broner entering the MGM Grand—to the ground.

The victim then proceeded to report the alleged assault to on-site security and law enforcement officers, who just so happened to have been already summoned to remove Broner from the premises for being too intoxicated. Efforts to issue a citation proved futile as Broner’s “current [intoxicated] state made it impossible to conduct a formal investigation into his side of the story on what happened taken place.”
