Someone edited a Pakistani child-safety education video to make it look like evidence of a ring of kidnappers was snatching children and taking them away on motorcycles; the video went viral in India, spread on Whatsapp, and it has inspired terrified mobs to attack and murder strangers on suspicion of being involved in the fictitious kidnapping rings.
The latest victims of the hoax are audio engineer Nilotpal Das and digital artist Abijeet Nath who were beaten to death when they stopped in a village in the state of Assam to ask for directions. Their murder was recorded and it, too, has gone viral -- it features one of the victims begging for his life as he is beaten.
There have been widespread protests over the hoax, with people chanting "don't believe the rumours."
The death toll from the hoax stands at eight. Dozens have been arrested for participating in mob violence.
