LONDON — London’s Tate Modern museum was on lockdown after a child fell from the building, witnesses and the Metropolitan Police said on Sunday.
A teenager was arrested in connection with the episode, the police said.
The circumstances of the fall and the conditions of the child were not immediately known, but images and video shared on Twitter showed an air ambulance helicopter landing on the grounds of the museum.
A police spokeswoman said the authorities were called to the museum about 2:45 p.m.
Some museum patrons said they were “trapped inside the Tate Modern” after a child had fallen or was “pushed from a balcony.” Others on social media said the museum had been evacuated, but it could not be confirmed.
Tate Modern, a museum of modern and contemporary art, has been one of the world’s most popular art museums since opening its doors in 2000.
Occupying a total internal area of more than 371,000 square feet, the vast space dominates one end of London’s Millennium Bridge, across the River Thames from St. Paul’s Cathedral.
Visitors often flock to the museum’s balcony on Level 10 to admire a 360-degree view of London. The viewing terrace opened as part of an extension in 2016 and it features some of London’s best sights, including St. Paul’s Cathedral; the Leadenhall Building, a skyscraper better known as the Cheesegrater for its distinctive appearance; the Houses of Parliament; and a swath of South London.
But the 10th-story viewing platform at the gallery offers views of luxury apartments with floor-to-ceiling windows in nearby towers. And in 2017, residents of four of the apartments mounted a legal challenge demanding that Tate close that side of the platform or at least put up screens, citing a “relentless” invasion of privacy from onlookers.
But in February this year the British High Court ruled against their case.
