This is the moment a mother is led to a jail in Mexico after she posted a live video on Facebook in which she and her boyfriend allegedly sexually abused her seven-year-old daughter.

Ana Gabriela Velasco, 32, was arrested last Thursday by authorities in the municipality of Chalco after she streamed the child being forced to pleasure her stepfather by touching him on Facebook Live.

According to Mexican news outlet Milenio, Velasco and José Luis López, who is also in his 30s, were participating in a sickening online challenge last Tuesday with another couple who were part of a swinger’s group.

The couple intended to save the video and then share it afterwards.

Instead, Velasco mistakenly clicked on the live video feed option on the social media network.

López, who is still being sought by local police, lay on the bed shirtless in the disturbing footage.

Velasco recorded the shocking incident on her cell phone and looked on as her daughter touched López.

Friends and family members tipped off authorities after catching wind of the heinous act.

The child's father saved the video to present as proof and showed it to the cops.

Investigators are still trying to determine if it was just an isolated incident or if others were partaking in similar practices.
