LONDON (REUTERS) - A teenager appeared in court on Tuesday (Aug 6) charged with attempted murder after a six-year-old French boy was reportedly thrown from a 10th-floor viewing platform at the Tate Modern art gallery in central London.

The 17-year-old male, who cannot be named for legal reasons, was arrested on Sunday shortly after the boy, who was visiting London with his family, was found on a fifth floor roof.

Bromley Youth Court was told the boy had sustained a bleed on the brain and fractures to his spine, legs and arms, Sky News reported. He is in a stable but critical condition in hospital.

The French boy's mother was heard by witnesses screaming: "Where's my son? Where's my son?"

Police said it was being treated as an isolated incident and that there was no link between the boy and the 17-year-old.

The teenager will be remanded in custody until Thursday when he is due to appear before London's Old Bailey court.

The Tate Modern, situated in a former power station next to the River Thames, was the most popular attraction in Britain in 2018 with almost six million visitors, according to the Association of Leading Visitor Attractions.
