The six-year-old boy who was "thrown" from the 10th-floor viewing platform at the Tate Modern gallery is no longer in a life-threatening condition at hospital.
The Metropolitan Police said the unnamed youngster, who is a French national visiting London with his family, was now “critical but stable”.
He was taken to hospital by air ambulance on Sunday after he fell from a platform at the central London art gallery and landed on a roof five storeys below.
A 17-year-old boy was arrested on suspicion of attempted murder shortly afterwards and remains in police custody.
A spokesperson for the Met said: “Officers continue to work hard to establish the circumstances of yesterday’s incident. Enquiries are ongoing.”
Police were also supporting the family of the injured six-year-old and said at the moment there was nothing to suggest he knew the teenager who is alleged to have hurled him over the railing.
Witnesses who were also at Tate Modern on Sunday said they heard a “loud bang” and then a woman screaming: “Where’s my son, where’s my son?”
Members of the public restrained the person they believed had thrown the boy off the platform before police arrived to arrest him.
Parts of Tate Modern, which was the UK’s most popular tourist attraction in 2018, were locked down for a time while officers responded to the incident.
Several people who saw what happened have given statements to detectives, the Met spokesperson added.
