"They just grabbed me and threw me on the floor and started hurting me."Witness video of the incident showed agents handcuffing the bleeding man as bystanders shouted.Jordan Salvador was there when Concepcion was beaten. He described the ICE agents as "very barbaric" and "super unprofessional.""You know, your job is to find undocumented people," Salvador said. "I get that, but it's just, there's ways to go about it."The agents finally asked for Concepcion's identification after he was in their vehicle. He said the agents admitted they made a mistake and let him go."They didn't want to talk to me. They wanted to kill me," Concepcion concluded. "And I told him. I ain't allow — I'm going to report them."
