(FOX News) -- A suicide "game" dubbed “Momo” has been spreading on WhatsApp, prompting police to issue warnings about the shocking challenge.
"Momo" is a viral challenge that asks people to add a contact via WhatsApp - they are then urged to commit self-harm or suicide. The "game" has fueled comparisons to the sinister "Blue Whale challenge" that led to reports of suicides in Russia and the U.S, as well as the online fictional character of "Slender Man." In 2014 two 12-year-old girls in Wisconsin attempted to kill a classmate in an attempt to please the horror character.
The Buenos Aires Times reports that police in Argentina are investigating whether “Momo” is linked to the suicide of a 12-year-old girl in the district of Escobar.

“Momo” is described as similar to the sinister "Blue Whale challenge," which is believed to be a social media group that encourages people to kill themselves, according to the Sun. “Momo” uses the creepy cropped image of a sculpture depicting a young woman with bulging eyes and black hair, News.com.au reports.
