BENGALURU: The deadly Blue Whale Challenge has found its roots in Bengaluru as two boys aged 18 and 19 remain in counselling against playing the game further. Lecturers of the second-year commerce students raised alarms as they caught the younger boy sporting an injured left wrist. Police authorities involved in the investigations said the boy's Whatsapp status read “I'm on the way” with a blue whale as a display image. “This raised suspicion among his classmates, who informed their principal. Understanding the severity of the game, authorities approached cops,” said Rani Shetty, head of Vanitha Sahayavani.
