Authorities in London say at least 88 people have been injured, seven of them seriously, after part of the ceiling collapsed at a theater.
London police say there were 81 walking wounded and that seven were taken to the hospital following the incident at the Apollo Theater. They say that so far, there are no fatalities.
The collapse occurred during a Thursday evening performance of The Curious Incident of the Dog in the Night-Time.
Rescue workers at the scene said all those trapped in the 775-seat auditorium by the collapse had been freed.
Witnesses said the ceiling simply collapsed during the performance, sending those inside the theater into a panic when they realized it was not part of the play.
Police said the cause of the collapse was not clear, but there was no indication that it was the result of any deliberate act or attack.
British Prime Minister David Cameron tweeted that he was "grateful for the fast work of the emergency services in helping the injured."
