Westminster City Council says health and safety checks on the Apollo Theatre, part of whose ceiling collapsed last night injuring 76 people, were up to date.

In a statement, the council’s cabinet member for community protection Councillor Nickie Aiken said that “we have no reason to believe this is other than an isolated incident”.

However she added, that, as a precaution, the Society of London Theatres has agreed to run further safety checks at all of the West End’s historic theatres today.

She added: “Our teams have been on site at the Apollo Theatre last night and again this morning and will remain on site until all checks are complete. As the investigation is ongoing, we are unable to comment further on specifics.”

The Apollo’s owner, Nimax Theatres, said the incident was “shocking and upsetting”. In a statement it added: “Our thoughts are with the audience and staff who were in the theatre and their families.”
