A British teenager pleaded guilty Friday to attempted murder for throwing a 6-year-old French boy from the 10th-floor viewing platform at London's Tate Modern art gallery.

Eighteen-year-old Jonty Bravery said "I plead guilty. Guilty, yeah correct" when asked during a court hearing how he pleaded.

The French child suffered fractures to his spine, arms and legs and a bleed on the brain after falling 100 feet (30 meters) from the open-air platform onto a roof in August. Prosecutor Emma Jones said it was “extraordinary” the boy had survived.

The victim can’t be named because of his age, but his family has said he is "now able to venture outside" and has regained some movement in his legs.

Police don't believe the victim and the suspect knew one another. Prosecutors said Bravery told police he had thrown the boy to prove a point to people who doubted he had mental health problems. He allegedly told officers: “I wanted to be on the news, who I am and why I did it, so when it is official no-one can say anything else."

Bravery’s lawyer, Philippa McAtasney, said the attacker had been assessed as having autistic spectrum disorder, obsessive compulsive disorder and likely a personality disorder. He is being held in a psychiatric hospital and is due to be sentenced in February.
