The roof of the Piccadilly Theatre in central London collapsed onto the audience this evening during a performance of Death Of A Salesman.
The building had to be evacuated after part of a ceiling fell onto members of the audience.
Several people suffered minor injuries after the incident in the West End and witnesses described hearing screams from nearby audience members.
Emergency services were called to the theatre shortly before 8pm after part of the ceiling crashed down into the auditorium.

The Metropolitan Police said a ‘few’ people had suffered minor injuries and that emergency services remained on scene.
Martin George, who was sitting in the Grand Circle, said there were screams coming from the audience as part of the ceiling came crashing down.
The 41-year-old said: ‘About 10 minutes into the performance you could hear this slight dripping sound in the [Grand] circle and people were looking around, wondering what was happening, but the play carried on.
‘As the minutes passed, the dripping became more frequent and it sounded like more water was coming through the ceiling, causing a few people to get up and move.
‘The sound eventually got so loud that we stood up and started to leave, as we were wondering what was going to happen.
‘Then, as we stood up, this huge chunk of ceiling, about three to four metres across, crashed down.
