A horrifying incident took place at the famed Tate Modern Art Gallery in London on Monday, Aug. 5, in which a 6-year-old boy was allegedly pushed by a 17-year-old boy from a 10th-floor balcony and is in intensive care.

People in the art gallery were in shock witnessing the 6-year-old boy fall from the exterior viewing platform on the 10th floor of the Blavatnik Building and landed on a fifth-floor roof, according to Daily Mail

His mother screamed, ‘He’s my son! He’s my son!’ and people from the viewing platform were screaming too.

The boy was treated at the scene and rushed to the hospital. A Metropolitan Police spokesman reported that the boy is in critical but stable condition.

A 17-year-old male was arrested on suspicion of attempted murder and taken into police custody, according to The Mirror. There is nothing to suggest that he is known to the victim.

In April 2019, a similar incident happened at the Mall of America in Minnesota where 5-year-old Landen was thrown over a third-floor railing, suffering head trauma, multiple broken bones, and his spleen removed. Twenty-four-year-old Emmanuel Deshawn Aranda was sentenced to 19 years in prison after pleading guilty to attempted premeditated first-degree murder in May.

After five months of treatment, Landen was recently reported no longer in intensive care.
