MADURAI: A 19 year old college student who was found hanging in his room, is reportedly Tamil Nadu's first death linked to the Blue Whale challenge. Police believe he was part of a Whatsapp group of 75 friends who were playing the suicide game. A note was found in his room, that read, “Blue Whale- this is not a game but danger. Once you enter, you can never exit.” Authorities also found a telling image of a whale carved into Vignesh's left arm and the words “Blue Whale” written below it. Vignesh was depressed and had been spending a lot of time alone in the last 45-50 days.
