A teenage boy was arrested after a Snapchat video showed him and several others bullying an 11-year-old girl.

The unnamed 14-year-old boy turned himself in on Wednesday, according to PIX11 News. He was charged with reckless endangerment and assault.

The incident happened on December 18 as the girl walked home from school with a classmate. When they encountered the group, her alleged friend reportedly began to film the interaction. The girl’s mother, only identified as Shevon, believes the attack was premeditated.

“It was a setup,” Shevon told the New York Daily News. “They already had it planned because he started recording even before they did it.”

In the video, several teens surrounded the girl and began to harass her.

“I don’t want to do anything. I don’t know you guys,” the sixth-grader told the crew.

"You can get to know us by putting my d**k in your mouth,” one of her assailants replied.

During the attack, one boy spat in a water bottle and poured it over her head before tossing the bottle at the girl. Another boy threw a backpack at the victim. Both were seen punching the girl.

When the girl eventually got home, she didn’t tell her mother about the attack.

“A friend from school called and said, ‘Your daughter is on Snapchat," Shevon recalled. “Kids were celebrating. They were congratulating one another. They were laughing at her.”

Shevon went to the police and said her decision to do so made her entire family a target. The family recently moved to Brooklyn from the Bronx. Now, they’re planning to return while her daughter was sent to Virginia to stay with relatives following threats from the boys and their parents, PIX11 News reports.

“I’ve been threatened because I went to the police,“ she said. “We really have to go. I don’t feel safe.”

Another suspect is still at large.
