A teenager has been charged with attempted murder after a six-year-old boy was allegedly thrown from a viewing platform at the Tate Modern art gallery. The 17-year-old is due to appear at Bromley Youth Court on Tuesday accused of trying to kill the child, who is a French national visiting London with his family. The youngster was airlifted to hospital after he was found on a fifth-floor roof at the gallery on Sunday afternoon. He is in a stable but critical condition. The boy had plummeted five storeys after allegedly being thrown from the 10th-floor viewing platform. Scotland Yard has said there is no link between the suspect and the victim.
