Per the Los Angeles Times, "Los Angeles police have arrested two men on suspicion of beating baseball fan Bryan Stow at Dodger Stadium and have concluded the suspect they took into custody in May was not responsible, a law enforcement source familiar with the investigation told The Times on Thursday.

"The developments mark a dramatic turnaround in the case. Until now, LAPD Chief Charlie Beck and other police officials expressed confidence that Giovanni Ramirez, a parolee, was responsible for the beating."

Updates as warranted.

Meanwhile, Stow continues recovering from emergency surgery earlier in the week.
