A horrifying scene Sunday afternoon in London, where a 6-year-old boy standing on a viewing platform on the 10th floor of the Tate Modern museum was thrown, falling five stories to land on a 5th-floor roof, the BBC reports. He is currently in critical condition, and police have arrested a 17-year-old male on suspicion of attempted murder. There is no indication of a relationship between the two.
A museum visitor who was on the viewing platform at the time said she heard a "loud bang," then turned around and saw a woman screaming, "Where's my son, where's my son?" Per CNN, she says she had previously noticed the teen suspect acting suspiciously; after the boy was thrown, bystanders reportedly restrained him. (The 5-year-old boy thrown from a Mall of America balcony in April just left intensive care.)
