WATCH: Mom chases down man who reportedly spied on 12-year-old daughter in store changing room

A mom's Facebook video featuring the shaming of a man who allegedly spied on her daughter in a clothing store changing room has gone viral — with millions and millions of views since Saturday.

What are the details of the incident?

Police arrested 36-year-old Jorge Leon-Alfaro at a retail clothing store on Saturday evening after he reportedly peeked under the changing room door of Doris Stiles-Scown's 12-year-old daughter.

The reported incident occurred at a Rue 21 outlet in Salt Lake City. Stiles-Scown said she discovered the man peeking under her daughter's changing room door and chased him out into the parking lot. Stiles-Scown, store security officers, and others detained Leon-Alfaro until police arrived on the scene.

"Certainly getting police on the way as fast as you can is the right thing to do," said Detective Greg Wilking of the Salt Lake City Police Department, according to KTVX-TV.

"We want to identify these individuals when stuff like this happens," Wilking continued, adding that officers were able to arrest Leon-Alfaro on voyeurism charges.

"It's very understandable [Stiles-Scown is] upset," Wilking said, but he offered a reminder about posting videos like this online: "The thing to remember about this is there is a criminal process to this and perhaps until waiting until the charges come is the better way to release something like that."

What about the video?

Stiles-Scown captured the whole incident on Facebook video, and it has been viewed more than 13 million times since she uploaded it to the social networking platform on Saturday.

Stiles-Scown captioned the video, which is rife with expletives, "Sick f***."

"This right here is what a predator looks like," Stiles-Scown says tearfully as she explains how she had to chase the suspect down after reportedly catching him lurking near her daughter's changing room.

"Not today buddy," Stiles-Scown says. The suspect looks at the ground throughout the entire video and does not make eye contact with Stiles-Scown, who is clearly upset and shaken. At one point in the video, she demands that he look at the camera, but he refuses.

"You're so lucky — so lucky — that I don't hurt you right now, 'cause that's what I want to do," Stiles-Scown says.

She later tells the suspect that her daughter's birthday was approaching in two days and that his actions would likely scar the young girl for the rest of her life.
