California deputies held three black teens at gunpoint after they were allegedly attacked by a man with a knife, video shows.

Tammi Collins, who is the mother of one of the teens, shared footage Saturday of two Los Angeles County Sheriff’s deputies pointing weapons in Santa Clarita Valley at the victims, who were off-camera.

Collins said her son and his friends were at a bus stop when they were attacked by a homeless man who asked them for drugs, then pulled a knife on them, CBS LA reported.

Bystanders called 911 to get help for them, only for at least three responding officers to draw weapons on the boys, Collins said.

In the video, some of the bystanders pleaded with the deputies to drop the weapons.

“Put the guns down. They’re just kids,” one of the bystanders could be heard saying.

“They don’t care because they’re black. They didn’t do nothing at all.”

A woman who identified herself as a manager of a nearby Buffalo Wild Wings tried to intervene, pleading with the cops to “please talk to someone.”

“I am the one that called you. It was not them,” she said.

Los Angeles County Sheriff Alex Villanueva said Monday that he has seen the video and the matter is under investigation.

“I have some concerns about the tactics involved,” Villanueva said in a video posted to Twitter.
