Updated at 7:24 a.m. Wednesday with additional information and to reflect that the victim is a man, not a teenager as previously reported.
Warning: The following video contains violence and explicit language.
A video making the rounds online shows a group of teens assaulting a man on DART’s Green Line train at the Deep Ellum Station late Sunday.
The cellphone video that’s about 2 minutes and 30 seconds long starts on the northbound train as the group punches and kicks a man. The fight then moves to the platform.
When the victim ends up on the ground, at least two of his attackers hit him with a skateboard as the others keep throwing punches. He’s last seen lying limp on the platform as the mob scurries back onto the train.
Authorities suspect about five teenage boys and two teenage girls participated in the beating, which occurred about 11:30 p.m., Dallas Area Rapid Transit spokesman Mark Ball said.
Kennan was taken to a hospital about midnight.
DART police initially used surveillance footage from the platform to investigate the attack. They became aware of the cellphone video Tuesday morning, Ball said.
Littmobtv, a company that shares videos from around the world, posted it to Facebook about 7 a.m. It has been viewed nearly 180,000 times by that time Wednesday.
When the Facebook video spread on Tuesday, Ball said they immediately acted on it.
“We made it a much more vigorous effort to try and get it resolved,” he said.
There’s another reason the department did not act sooner, said Ball.
“We did not pursue it vigorously because the individual did refuse to pursue charges,” he said.
It’s a claim that Kennan disputes.
“I never said ‘no,'” he said.
As the train pulled away from the station, the man remained motionless on the ground.
DART said after seeing the brawl unfold on their cameras on the platform, they immediately dispatched police officers and Dallas Fire-Rescue. The victim was taken to Baylor University Medical Center in Dallas at 12:02 a.m. for treatment.
DART police are investigating the incident and said if they can identify who took part in the assault they will press charges.
The investigation into the incident is ongoing. DART said they are comparing faces in the video posted to social media with their video recorded on the platform.
