Officials in the U.K. have concluded the owners of a London theatre should not face prosecution over a ceiling collapse which injured 88 audience members during a production of The Curious Incident Of The Dog In The Night-Time.

The Apollo Theatre was the scene of a major disaster last December (13) when parts of the roof began falling on the crowd while they were watching the acclaimed show.

Emergency services descended on the venue to help the injured, and local officials at Westminster City Council subsequently launched an investigation.

They concluded the disaster was caused by the deterioration of cloth and plaster ties which were holding up the timber ceiling frames, which had been in place since 1901, but they have now announced no charges should be filed because they found "no breach of the current laws".

However, council leaders are urging theatre groups to bring in more strict rules governing ceiling inspections in historic buildings.

Councillor Nickie Aiken says, "This has been one of the most thorough investigations of its type, and our main aim now is to ensure that an accident like the one at the Apollo never happens again..."

Nica Burns of Nimax, the company which owns the theatre, adds, "I welcome the conclusion of the Westminster investigation, which confirms it was a terrible accident. Not a day has passed where I do not think about every single audience member, the cast and staff present on that December evening. My heart goes out to all those affected by that night. I would like to again extend a big thank you to emergency services and my fantastic team at the theatre for their fast and effective response."
