A six-year-old boy is in a critical but stable condition after he was “thrown” from the 10th floor of the Tate Modern art gallery in London.
The child was found on a fifth floor roof after he fell from the viewing platform on Sunday afternoon.
A witness said they heard a “loud bang”, before seeing a woman scream: “Where’s my son, where’s my son?”
A 17-year-old boy arrested on suspicion of attempted murder remains in police custody.
The Met Police said there was nothing to suggest he was known to the victim.
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.
