Random act of culture closes mall

Bizarre:

Thousands had gathered at the shopping mall's food court to take part in a group rendition of Handel's Hallelujah Chorus as part of a flash-mob concert – when groups of people – often strangers – conspire on social networking websites to turn up at the same place at the same time and start singing.

 

But, as they burst into song, there were reports that the building's floor began to move and creak, and witnesses reported hearing popping sounds.

 

Emergency services were forced to evacuate the entire building.
