London — U.K. police descended on a yoga class in central England after a member of the public spotted people lying on the floor and reported a "mass killing."

Officers rushed to the spot with their sirens blaring only to find members of the class quietly meditating.

The Seaside Cafe inside the North Sea Observatory in Chapel St Leonards said a worried member of the public raised the alarm on Wednesday night after becoming concerned.
