In Uruguay, a mother was arrested for abusing her daughter and promoting photos via WhatsApp.
The detainees are accused of storing and exchanging pornographic files, which in some cases were "extremely serious".
According to the publication in question, the police discovered that "a group of minors on WhatsApp were distributing child pornography material or even sexually abusing other minors".
In addition to exchanging files, the detainees allegedly distributed small digital images such as easy-to-move emojis showing "very young children being abused."
One of the detainees, 29, not only promoted child pornography but also encouraged members of the group to come into contact with young girls who could be exploited, especially immigrants who find it theoretically more difficult to seek help from the police.
