Police on Thursday arrested one person in the brutal beating of a Dallas man who was attacked after asking a group of teens to stop smoking marijuana.

A Dallas Area Rapid Transit spokesman said the agency arrested Jakobi Darion Hendrix, 21, in connection to Sunday’s beating, which was captured on video.

The arrest came hours after police said they had positively identified some of the suspects. Police have not released all of their names.

Cell phone footage showed teens punching, kicking and slapping Kennan Jones. Others joined in to attack him – but no one tried to help. When Jones tried fighting back, a girl hit him on the head with a skateboard, knocking him unconscious.

Two people who took part in the beating were seen wearing Whataburger uniforms. A restaurant spokesperson released a statement to Fox 4 in Dallas-Fort Worth saying the company is appalled by what happened and is working with police to help in the investigation.
