Five 12-year-old boys have been implicated in a sex scandal in a school in Mexico, after a mother exposed a video showing three of the boys performing sexual acts with each other.

The minute-long graphic video shows three boys performing oral and anal sex while one boy filmed and another watched. The mother of one of the boys discovered the video on her son’s cellphone and filed an immediate complaint with the Attorney General. The case is currently under investigation as they attempt to determine if the participants were coerced to create the video.

The incident occurred in the Mateo Reyes school in the city of Calkini, a relatively conservative area.”It is real, the case is real, the video exists,” explained State Education Department spokesman Omar Kantun. “The Education Department is very concerned.”

The boys are currently receiving psychological counseling.
