Atlanta police on Saturday announced they had arrested a suspect in the beating of Brandon White, a gay man.

Three men beat 20-year-old White on February 4 outside a southwest Atlanta store. The beating was captured on video and posted online. In the video, the men can be heard shouting anti-gay slurs at White as passersby look on.

Police spokesman Carlos Campos said that Christopher Cain, 18, had been charged with aggravated assault and robbery and that the police are still seeking the two other suspects. The men could also face hate crime charges, federal investigators said.

“I feel as though I should have justice,” White said during a press conference last week, “because those guys didn't feel my pain. They didn't care whether or not I was injured. I could have died that day. They're monsters.”

The Atlanta Journal-Constitution reported that U.S. Rep. John Lewis joined a Saturday rally in support of White. He urged the crowd to continue speaking out against crime: “When you see something going wrong, you must do what you are doing today.”
