The injuries suffered by a six-year-old boy who was allegedly thrown from a viewing platform at the Tate Modern art gallery have been revealed in court.

The unnamed boy, who is believed to be French and was holidaying with his family when he was attacked on Sunday, suffered a bleed on the brain and fractures to his spine, legs and arms.

A 17-year-old boy appeared at Bromley Youth Court on Tuesday accused of attempting to murder him.

The child, who is in a stable but critical condition, had plummeted five storeys after allegedly being thrown from the 10th floor viewing platform.

The 17-year-old, who cannot be named for legal reasons, wore a grey jumper and spoke to confirm his name, address, date of birth and nationality as British at the short court hearing.

The teenager, who appeared in the dock, was remanded in custody to appear at the Old Bailey on Thursday.

Scotland Yard has said there is no link between the suspect and the victim.

Officers were called to the gallery at around 2.40pm and the child was treated at the scene before being flown to hospital by London’s Air Ambulance.

The Tate Modern was the UK’s most popular tourist attraction in 2018 after being visited 5.9 million times, according to the Association of Leading Visitor Attractions.
