A 17-year-old boy charged with attempted murder appeared at Bromley Youth Court today for a short hearing.

The teenager is suspected of "throwing" a six-year-old boy from a 10th-floor balcony at the Tate Modern on Sunday, August 4.

The court heard the child sustained a bleed on the brain and fractures to his spine, legs and arms after allegedly being thrown.

He is a French national and remains in a stable but critical condition after plummeting five storeys down.

The suspect, who cannot be named for legal reasons, wore a grey jumper at today’s hearing.

He is a British national and confirmed his name, address and date of birth to the court.

The court was told how the little boy was "looking over the side and enjoying the view" before being thrown from the building.

He was allegedly picked up and tossed over the edge.

It was "carried out extremely swiftly and in one moment" the court was told.

The suspect was apprehended by members of the public afterwards.

He has been remanded to youth detention accommodation until a hearing at the Old Bailey on Thursday.

Police don’t believe there is a link between the suspect and the victim.

The six-year-old boy injured in the fall was airlifted to hospital after he was found on a fifth-floor roof at the gallery on Sunday afternoon.
