A 17-year-old male was arrested for throwing a 6-year-old boy off of the 10th floor of London’s Tate Modern Gallery.

The teen is being described as a ‘French national’ who was visiting the UK with his family.

Police are holding the teenager in custody on suspicion of attempted murder.

The boy was airlifted by helicopter to a nearby hospital after he was thrown from the 10th floor and landed on a 5th floor roof.

France 24 reported:

A six-year-old boy thrown from a tenth-floor viewing platform at London’s Tate Modern gallery is a French national who was visiting the British capital with his family, police said Monday. The boy is no longer in a life-threatening condition, according to London’s Metropolitan Police, who appealed for further witnesses to the Sunday afternoon incident to come forward. A 17-year-old boy who was initially detained by members of the public on the tenth-floor platform and then arrested by officers, remains in custody on suspicion of attempted murder. “This is being treated as an isolated event with no distinct or apparent motive,” senior investigating officer DCI John Massey said in a statement, adding there was no known link between the victim and the teen arrested. He said the victim was now in “a stable, but critical condition in hospital with his family”. Massey asked anyone in the vicinity of the viewing platform who might have witnessed the incident but left immediately afterwards in shock to contact police.

According to witnesses, the little boy’s mother was looking around and screaming for her child after he was thrown from the building.

This comes several months after a little boy was thrown off the balcony of the Mall of America in Minnesota.
