LONDON — Owners of all historic theaters in Central London carried out safety checks on their buildings Friday following the collapse of a ceiling that injured 76 people at the 112-year-old Apollo theater.

During a performance of “The Curious Incident of the Dog in the Night-Time” at the theater Thursday, large chunks of ornate plasterwork fell on the audience.

Seven of those hurt have serious injuries, and two remain in hospital.

Officials for Westminster City Council, the governing body that controls Central London, are due to report later today on the structural assessment of the theater, the BBC reported. The body confirmed the theater’s health and safety checks were up to date.

Nickie Aiken, cabinet member for community protection for Westminster, said: “As a precaution, all historic theaters are carrying out further safety checks.”

Mhora Samuel, from The Theaters Trust, said: “This was a very, very rare thing to have happened. The public should be completely reassured that all the theaters in the West End are safe.”

Performances at the Apollo have been cancelled until January 4. The Society of London Theaters said all other theaters in the city remain open for business.

There has been speculation that stormy weather in London on Thursday may have played a part in the accident, with multiple lightning strikes across the city.

Some of those who were in the theater claim they saw water trickling through cracks in the ceiling before it collapsed.
