An Ealing teenager who threw a six-year-old boy from the Tate Modern viewing gantry has been told he "may never be released"

18-year-old Jonty Bravery, who has autism, has been jailed for at least 15 years for attempted murder.

Old Bailey judge, Mrs Justice McGowan said his mental disorder did not explain the attack, and acknowledged Bravery presented a “grave and immediate risk to the public”.

In August last year, the victim survived a 30m fall but suffered life changing injuries.
