Old theatre roofs at risk of collapse?

24 March 2014 Last updated at 07:11 GMT

A ceiling collapse at London's Apollo Theatre in December has been put down to weak and old materials, the BBC has learned.

Radio 4's You and Yours programme has seen an official letter from Westminster City Council that said hessian wadding embedded within the ceiling was getting weaker over time.

It has now sent out a letter to historic theatres in the West End recommending that all suspended ornate ceilings are thoroughly inspected as a matter of urgency, as Lisa Hampele reports.
