The video shows two girls physically fighting, with a third girl seemingly attempting to chime in nearby.
Chade Lockett, the mother of one of the two girls in the altercation, is seen drawing a handgun and pointing it at the girl, whom she appears to chase after.
The two girls, 13 and 15 years old, continue to fight and Lockett runs in and tries to break it up, seemingly trying to break the girls apart.
They continue to fight and pull each other’s hair while the mother circles the scene.
The argument stemmed from an issue the girls had on Snapchat, KTRK-TV reported.
Lockett told the station the video doesn’t tell the whole story, and the weapon was actually her son’s toy BB gun.
She said: “I went back to the car to get the BB gun when I saw they had knives.
“It was either the crowbar or the BB gun.
“I chose the BB gun. It looked realistic. It was 15 of them and two of us.”
The video does show a woman holding what looks to be a knife.
Veneisha Jones, who recorded the video, said Ms Lockett “pulled a gun out on us. We were frightened for our lives.”
Ms Jones told the news outlet that the girls who were fighting were 15 and 13 years old.
She said: “They’re both teens, they fight and get into it, that’s what teens do.”
She added Ms Lockett “had no reason to put her hands on her or anything like that.”
A police report has been filed with Houston Police.
It is understood that the fight started over a Snapchat row, and started at another location prior to the video.
