The Mumbai Police also issued a warning against the deadly online game, which challenges young boys and girls to communicate with an unknown number. “How about interacting with us on the widely known #Dial 100 than on unknown numbers, to beat the challengers in their own game!” says the police. With their unique hashtag, Mumbai Police posted on Twitter warning people to say no to the Momo Challenge. “Not all momos are meant to be consumed”, was the message highlighted by the Police with a photo of a plateful of edible momos, with one having the scary doll's face, that has been used by the social media account.
