Ushers working in West End theatres have started wearing body cameras to try and stop increasing levels of aggressive behaviour from audiences.

Theatre directors say recording what can be violent situations will help staff feel more empowered and trials show people often back down when they see they're being recorded.

The Society of London Theatre has teamed up with a security company to give body cameras to front-of-house staff.
