BBC's The One Show taken off air by fire alarm
BBC One's The One Show was taken off air when a fire alarm went off during Wednesday's live broadcast.
Presenters Matt Baker and Alex Jones were interviewing actress Tamsin Greig at the time.
After several minutes of confusion, the 7pm show was taken off air and a recording of cooking show Simple Suppers filled in.
Later Jones revealed on Twitter: "Somebody was warming their tea up and the microwave set off the alarm!"
She added: "That's live telly for you!"
A BBC spokesman said there had been no fire at the BBC studio in White City, west London, where the weekday magazine show is filmed, but a handful of people had been evacuated.
She said: "The One Show went off air tonight due to a fire alarm. We apologise to viewers for the interruption and normal service was resumed on BBC One as soon as possible."
