Seventy-six people have been injured, seven seriously, after part of a ceiling in London's Apollo Theatre collapsed during a show, police say, according to BBC News.

The venue in Shaftesbury Avenue was packed for a performance of The Curious Incident Of The Dog in the Night-Time.

Eyewitnesses heard "a crackling" noise before the collapse at about 20:15 GMT. Theatre-goers left covered in debris.

The Apollo's owner described it as a "shocking and upsetting" incident and said an investigation was under way.

A spokesman for the company, Nimax Theatres, said "thoughts are with the audience and staff".
