A Mexican woman is under investigation for using her Facebook account to put her son up for sale.

The woman, identified as Brenda Raymundo, shared photos of her 5-year-old son on the social media outlet and explained that she couldn't stand the kid anymore and wanted to sell him for 15,000 pesos or just over $830 U.S. dollars.

"What a nuisance this boy is, anybody want him?" she wrote along with photos of the child.

A Mexican reporter found out about the woman selling her son and wanted to see if the advert was for real or if it was just another hoax.

The reporter, Yohali Reséndiz, contacted the number provided by Raymundo on Facebook and revealed that a woman, most likely Raymundo, answered her.

Reséndiz said that while on the phone she heard children crying in the background and was told by the woman that the sale was "serious" and that she didn't want any tricks.

Raymundo's Facebook account has since been removed and authorities in Tlaxcala, Mexico are currently investigating the well being of the child.

This isnt the first time that something like this has happened on Facebook. Last year a father, Arturo González, attempted to sell his 9-year-old daughter as a sex slave and in 2013 an Oklahoma mother tried selling her children on the social media platform for bail money to get her boyfriend out of jail.
