A Houston, Texas man is recovering from a brutal beating he suffered Sunday night on a Houston DART train.

The attack on 44-year-old Kennan Jones was filmed by a witness to the beating and began when Jones, on his way home from night classes, asked a passenger to not smoke marijuana in the train.

“When they started smoking I’m like, ‘Come on, man. We’re on a train. Can y’all just wait? Just wait,” Jones told NBC DFW.

A young woman in the group had words with Jones and spit in his face.

“I was like, ‘You lucky I don’t hit females, little girl, because I would beat your ass for that. And that’s when everything went from zero to 100,” Jones said.

The video appears to show a group of five men and two women began slapping, kicking, and hitting Jones, cornering him in a small doorway. Other passengers stood by as Jones tried to defend himself.

When the train stopped at the Deep Ellum station the beating continued on the platform and ended when someone hit Jones with a skateboard.

At that point DART police were notified and it took between 10 and 15 minutes for them to arrive. By then, the attackers were gone.

DART spokesman Mark Ball told NBC DFW that trains do not have surveillance cameras on them, so it wasn’t until the brawl spilled out to the platform that security knew what was going on.

Now that authorities have the bystander’s video, however, “We made it a much more vigorous effort to try and get it resolved,” he said.

Further hampering the investigation is the fact that Jones reportedly initially refused to press charges.

DART police are actively investigating the incident and anyone with any information is asked to contact DART police at 214-928-6300.
