Police worldwide are warning parents of a disturbing new internet challenge that may encourage suicide.
The "Momo challenge" asks the user to add a new contact called "Momo" who then sends a barrage of images and violent messages encouraging acts of violence or suicide.
According to the Buenos Aires Times, the challenge is possibly linked to the death of a 12-year-old girl from Argentina who apparently took her own life. If confirmed by police, the girl would be the first victim of the disturbing challenge.
The challenge seems to be circulating primarily through WhatsApp and Facebook, and authorities aren't sure of the perpetrators' motive.
