Mark Haddon, the author of The Curious Incident of the Dog in the Night-Time, has said he is "hugely relieved" that no-one was killed this tonight's collapse:
It's been horrifying sitting here watching what has been happening at the apollo this evening. I'm hugely relieved that no-one has died...
... & i hope that those who were seriously injured are OK. I'm sorry, too, that so many people went through such a terrifying experience.
