Just when you thought that evil Momo character was gone cops are warning that the character is back in “Baby Shark” videos.  The character caused hysteria earlier this year when the “Momo Challenge” caused kids to harm themselves and some kids even committed suicide.  The scary looking female is said to pop up in the videos and ask kids “to pick up a knife and cut their hands ” and if they don’t “Momo will come after you.”   Police are asking parents to supervise what their kids watch online and to support anything suspicious.
