Face of Nation : He landed on a fifth floor roof and was taken to hospital by air ambulance after he fell at about 14:45 BST on Sunday. The boy’s condition is described as critical. A 17-year-old boy has been arrested on suspicion of attempted murder, the Met Police said. They said the six-year-old was thrown from a viewing platform. A police spokesman said there was “nothing to suggest [the suspect] is known to the victim”.
The teenager had remained on the platform after the boy fell, police said. Visitors were initially locked inside the gallery at Bankside on the South Bank. Eyewitness Stuart Haggas said he saw emergency crews moving along the roof between the gallery’s Turbine Hall and its recent extension.
“They were carrying a stretcher with someone on it,” he said, “plus a second stretcher was waiting by the door.” “There were at least two fire engines, 10 police cars and an incident control unit. Parts of the exterior of the building were taped off.” The Tate Modern opened in the disused power station on the River Thames in 2000. It was the UK’s most popular tourist attraction in 2018 with 5.9m visitors, according to the Association of Leading Visitor Attractions.
