A teenager who threw a child from a tenth-floor viewing platform at the Tate Modern reportedly spoke of a plan to push someone from a high building a year earlier it has emerged. A recording released of convicted teen Jonty Bravery, allegedly hears him telling one of his carers about how he would kill someone and go to prison, saying: “I know for a fact they'll die from falling.” "In the next few months I've got it in my head I've got to kill somebody," Bravery said in the shocking recording from autumn 2018 that was obtained by the BBC and the Daily Mail. He added: "It could be the Shard, it could be anything just as long as it's a high thing and we can go up and visit it and then push somebody off it and I know for a fact they'll die from falling from a hundred feet.” Bravery went on to throw a six-year-old boy over the railings of the famous London art gallery. The child suffered a brain injury, broken arms and legs, and a fractured spine when he landed on a fifth floor roof at the tourist attraction. The boy was with family at the world-famous art gallery when the incident happened. Witnesses reportedly heard his mother shout “my son, that’s my son” as he fell five floors. The Tate Modern was the UK’s most popular tourist attraction in 2018 after being visited 5.9m times, according to the Association of Leading Visitor Attractions, and would likely have had thousands of visitors on that Sunday. The teenager had spoken of a plan in the clip, which was shared by one of Bravery’s former carers, just months before the horrifying incident at the Tate on 4 August 2019. The former carer who shared the footage said it was not the first time Bravery had spoken about his plan. They said he told a more senior colleague about what the teenager said and that they also played the clip to someone else involved in his care, but they both denied this. In a statement, Bravery’s care provider Spencer & Arlington said they had "no knowledge or records of the disclosure" of any care plan, care report or review from managers or Bravery's carers, psychologists, or health workers. Meanwhile, the little boy, who cannot be named for protection purposes is now able to move his limbs with the help of a ‘full armour of splints’.
