Three people have been shot outside of a barbershop following an argument between two men in their 40’s allegedly over who came first in a foot race over a month ago.

The incident occurred at approximately 3 p.m. on Saturday, July 10, in northeast Houston when the Houston Police Department received a call regarding a shooting involving several victims outside the Mean Kutz barbershop, according to ABC News’ Houston station KTRK.

“There were two males that were arguing outside the barbershop here over who ran a race faster,” said Houston Police Department Assistant Chief Wendy Baimbridge told KTRK in a short press conference following the shooting. “So at that point, one of the victims started walking away from the argument. The suspect then shot him twice in the shoulder.”

Two innocent bystanders who were inside the barbershop at the time were also struck in the shootout. One was shot in the rear end while the other was shot in the arm, according to Baimbridge.

The suspect who initially began firing subsequently fled the scene of the crime traveling eastbound away from the barbershop in a black Nissan Frontier. Authorities said they do not have the vehicle’s license plate at this time.

The Houston Police Department confirmed that they have gathered video evidence from the phone of a witness as well as surveillance footage from a liquor store next to the barbershop.

One victim was taken to Kingwood Hospital to be treated while the other two were taken to Memorial Hospital. None of the three people who were shot suffered life-threatening injuries and all are expected to survive.

“I just came to get a haircut but that didn’t go as planned,” said one woman who witnessed the shooting.

The suspect is currently at large and major assault detectives are currently investigating the incident. Anyone with information is asked to contact Houston Police Department’s Major Assault Division or Crime Stoppers.
