'She was in the clutches of a toxic digital world': Mother of dancer, 15, who threw herself in front of train after creating online cocaine fantasy warns parents to beware what their children are up to on the internet Inquest jury records narrative verdict over death of Tallulah Wilson Her mother Sarah pays emotional tribute to 'a beautiful shining star' Urges other parents to keep their children away from 'toxic digital world' The mother of a teenage ballerina who threw herself in front of a train today issued a heartfelt appeal urging parents to be aware of the dangers posed by the 'toxic' internet. Private school pupil Tallulah Wilson, 15, became obsessed with the web and created a cocaine-taking fantasy personality in a bid to escape reality, an inquest heard, After the jury at St Pancras Coroner's Court delivered a narrative verdict, the dancer's mother Sarah paid tribute to her beloved daughter. Talented: Tallulah Wilson was a promising dancer who had been 'headhunted' by the Royal Ballet 'Our lives will never be the same without Tallulah,' she said in a statement. We have lost someone more precious than words could ever say - a beautiful, loving and talented shining star has been stolen from our skies. She said that she had tried to keep her daughter safe by liaising with teachers and health workers, but the 15-year-old had already fallen into the clutches of her second life online. 'Her sisters and I did everything we could to keep her safe, but she had fallen into a world of nightmares,' Mrs Wilson said. She was in the clutches of a toxic digital world where in the final few weeks we could no longer reach her. I was shocked by the ease with which Tallulah and other children can access online self harm and suicide blogs. She added: 'Tallulah entered a world where the lines between fantasy and reality became blurred. It is every parent's worst nightmare. I believe the likes of Tumblr should do more to protect other vulnerable young people from the insidious aspects of the internet - they need to take an active role in policing and swiftly removing unsuitable material as some sites already do. I appeal to big brands to withdraw their advertising from those sites who continue to host inappropriate self-harming and suicide-promoting blogs to stop this poison spreading. My family has suffered an irretrievable loss and would now appreciate some time to reflect and come to terms with a world eclipsed without Tallulah, but every parent needs to be aware of the dangers of the internet and what their children may be viewing online. Anna Thwaites, the family's solicitor, said: 'This is a tragic case. More needs to be done regarding the perils of the internet and the impact this has on our children. The inquest jury said at the end of their verdict: 'This case has highlighted the importance of online life for young people. We all have a responsibility to gain better understanding of this. This is a particular challenge for healthcare professionals and educators. Coroner Mary Hassell said she would make a prevention of further deaths report following the inquest. The inquest heard that the teenager from West Hampstead, north London, who once reportedly head-hunted by the Royal Ballet School, would go online and post pictures of herself with self-inflicted cuts. Torment: The teenager moved from St Marylebone School in St Pancras after suffering at the hands of bullies Detective Sergeant Adrian Naylor, of British Transport Police, said last week that materials including computers, diaries and a journal had been taken from Tallulah's home as part of an investigation into her death, which occurred on October 14 2012. Tribute: The mother of Tallulah Wilson, who died in 2012, has spoken of her grief at losing her 'beautiful shining star' He told the hearing there had been 'disturbing writings relating to self-harm and self-loathing' in a journal that was taken from the house. One picture of self-inflicted injury on a computer had been captioned 'my arm', he said. The inquest heard that consultant psychiatrist Dr Andrew Wiener, of the Tavistock and Portman NHS Foundation Trust, had assessed the teenager as being severely depressed when he saw her in May 2012. 'Her mother is a normal caring parent, who had conflict with her daughter,' they said. She had difficulties with some girls at St Marylebone School in St Pancras and created an online persona. 'Her mother expressed her concerns and highlighted the dangers of this activity and the possible consequences,' the jury said. During this period Tallulah started to self-harm, which was noticed by the school nurse. After leaving the school and moving to St Margaret's School in Hampstead she attended sessions with a consultant psychiatrist who diagnosed severe clinical depression, prescribing anti-depressant medication and talking therapy. On October 8 an online account was deleted at her mother's request. 'This contained inappropriate images containing self-harming behaviour,' the jury said. This resulted in conflict between Tallulah and her mother. 'This site was very important to Tallulah, providing her with a medium to express herself over which she had total control,' the jury said. On the day she died she was driven to dance class by her grandfather, but did not attend. It is unclear whether she was depressed at the time that she took her own life, the jury said. New school: Tallulah moved to £11,000-a-year St Margaret's School in Hampstead a month before her death
