WATCH: Phoenix Shooting Under Investigation as Hate Crime

Police in Phoenix are investigating a shooting at a Mexican restaurant as a potential antigay hate crime, reports TV station KPNX.

Two groups of people got into a fight at Julioberto's about 3 a.m. today, and what started as a verbal altercation became physical as the parties took it outside, the station reports. One man left after making antigay remarks to the restaurant cashier, then returned with a gun and fired into the restaurant, shooting a woman in the hand, a witness said.

"He was talking [expletive] about us because we were gay," the witness, who asked not to be identified, told the station. "Someone else asked him, 'What's your problem?' and he didn't think twice. He ran away to his car and got [the] gun."

The woman, whose name was not disclosed, sustained non-life-threatening injuries, KPNX reports. Police are reviewing security camera video, which may have captured the shooting, and interviewing witnesses to the incident.

"We do have information that this was a possibility a bias incident, that it involved name-calling and things of that nature," Officer James Holmes told KPNX. "And so certainly we're going to investigate it with the information we have as a possibility."
