GAHANNA, Ohio (WCMH) – A video sent to NBC4 Tuesday shows a chaotic scene involving a traffic jam on Interstate 270, with some cars trying to pass anyway and also trying to dodge two men attacking each other.

“After eight years of being a truck driver I thought I seen it all, but just when you think that, something else happens,” said Jon Castiaux, who witnessed the incident Saturday morning on I-270 South as he waited in halted traffic.

Castiaux told NBC4 that he was approaching the Hamilton Road exit when he saw people running around on the highway. He then spotted two men on the ground and was under the impression at first that someone was getting CPR.

“I immediately thought it was a bad accident with an ejection,” Castiaux said. “As I got closer I noticed punches and kicks started flying so I just pulled my phone out to record it just to honestly prove that it happened.”

The video showed the two men — one wearing a black shirt and another in a blue shirt — struggle with each other on the ground briefly, while other people got out of their cars and stood nearby. Another man ran across the highway and appeared to gesture at the cars before running off. The two men then got up, losing their shoes in the process, and the one in the black shirt proceeded to kick and fling his hands at the other, knocking him down again.

Castiaux’s phone tilted down after this, so it’s not clear what happened next. When the camera came back up, the man in the blue shirt charged at the man in the black shirt, throwing a punch. More drivers in the traffic jam had gotten out of their cars and watched as the fight continued. Fed up with waiting, another driver weaved around on the right-side curb and kept going.

The man in the black shirt then began running away, picking up one of his shoes as he headed for the median, and the other man chased him. The video showed a red truck trying to pass the jam nearly clipping him as it tried to get around. Another witness moved closer to the fight and appeared to try to talk to the two men. It did not appear to work, as the two men ran further up the highway.

At this point, Castiaux’s camera showed a car stopped in the median, which has a sign marking U-turns as not allowed. The video ends before the two men stopped again, but they appeared to be running toward that car.

“I’ve been trying to figure out why it even happened,” Castiaux said.

NBC4 reached out to the Gahanna police to learn more about the aftermath of the fight. They said that by the time officers got to the scene, the fight was over. None of the people involved wanted to cooperate, and others were already gone.

Officers did not make any arrests related to the fight, according to Gahanna police.
