CHENNAI: A 24-year-old student sustained severe injuries after she jumped from her seventh floor flat in Virugambakkam around 11pm on Monday, landing on a car parked below.Police on Tuesday said J Niveditha broke her back in the fall and doctors treating her at a private hospital described her condition as serious but said she was out of danger.An investigating officer said police are looking into a possible connection between the attempted suicide and the so-called `Blue Whale' challenge -an online game that law enforcement agencies worldwide are probing.Reports have attributed numerous deaths to players receiving tasks from the game's administrators over 50 days, the final one demanding that the player commit suicide. Neighbours told police that she had been looking depressed for the past few days and that she may have been playing the game. Police started the investigation into a link with the game after neighbours told them that Niveditha had appeared to be depressed for a few days prior to the attempted suicide and raised the possibility that she may have been playing the game.Niveditha, an only child who lives with her parents in a posh apartment complex on Arunachalam Road in Virugambakkam, is pursuing a master's degree in computer applications ( MCA )."Witnesses said Niveditha leaped off a balcony from her 7th floor apartment," the officer said. "She appears to have acted deliberately , opening a grille door to get to the balcony.""A few neighbours and a security guard at the apartment complex heard a loud sound and found Niveditha bleeding profusely on the roof of a car," he said. "The woman's parents and neighbours took her to a private hospital nearby." "Niveditha's parents said they knew nothing about her playing the 'Blue Whale' game online but we are checking call data from her cellphone to see for ourselves," the officer said, adding that they were waiting for her to regain consciousness so they could speak to her. "We are also looking at the possibility that other causes prompted the suicide," he said.The government had on August 11 directed internet majors like Google , Facebook, WhatsApp Microsoft and Yahoo to immediately remove all links to the Blue Whale game. Prior to Monday night's suicide bid, police forces across India were probing connections to the game in at least three deaths and two attempted suicides.Though authorities in Russia -where police have arrested at least two men for "inciting at least 16 teenage girls to kill themselves" -and elsewhere are investigating the scores of cases, some internet experts believe the phenomenon is a hoax.
