Teen arrested for attempted murder after boy is thrown 5 stories off Tate Modern viewing platform The incident occurred on Sunday afternoon in London.

LONDON -- A 6-year-old boy is in a critical but stable condition with head injuries and multiple broken bones after being thrown five stories from the Tate Modern in London, the U.K.’s most popular tourist attraction.

The boy was visiting the modern art gallery’s 10th floor viewing platform with his mother Sunday when he was taken from her arms and thrown over the railing, according to the Daily Mail. He landed on the roof of a five-story building about 100 feet below.

The young victim was a French national visiting London with his family, the BBC reported.

Police were called at around 2:40 p.m. local time and were accompanied by the London Ambulance Service and London’s Air Ambulance. The boy was treated at the scene and then taken to the hospital by air ambulance.

On Tuesday officials said he had suffered a brain injury and a fractured spine, as well as fractures to his arms and legs.

Police at the scene arrested a 17-year-old male on suspicion of attempted murder. He is due in court at the end of the month.

A witness told the BBC that they heard a “loud bang” after the child was thrown.

BBC journalist Olga Malchevska happened to be on the viewing platform with her own child at the time. “People started to push each other,” she said. “Then I saw that woman who was running and shouting, ‘My son, oh my son.’”

Malchevska said that railings around the platform reach shoulder height and that there was no reason to think that the platform was unsafe.

“We were close to the viewing gallery on the tenth floor, that’s where he was pushed,” Tate visitor Nancy Barnfield told the Telegraph. “Then there was a loud bang and people rushed in to restrain him, it was mostly men. They held him for ten minutes before police arrived. His face showed no emotion, he was completely silent.”

The police said there was no reason to suspect that the teenager was known to the victim.

“Tate is working closely with the police,” a gallery representative said on Twitter. “All our thoughts are with the child and his family.”

The gallery was closed for the remainder of Sunday. It re-opened Monday morning, but the Level 10 viewing platform remained closed.

Last year the Tate Modern became the most visited tourist attraction in the U.K., welcoming 5.86 million people in 2018, according to the Association of Leading Visitor Attractions.

Sunday's incident is similar to one that occurred in Minnesota in April when a child was thrown off the third floor balcony of the Mall of America. The victim spent almost four months in intensive care before being moved on Aug. 2 to an inpatient physical rehabilitation program at another hospital.
