A 17-year-old British teen has been charged with attempted murder after a 6-year-old boy was allegedly thrown from a 10th-floor viewing gallery at Londons Tate Modern museum on Sunday.

The child, a French national, remains hospitalized in critical but stable condition after plunging several stories during a visit to the museum with family, Metropolitan Police said Tuesday.

Police have said that the victim and the suspect, who is not being identified because of his age, did not know each other.
