Westfield Stratford City was evacuated this morning after contractors accidentally set off a fire alarm.

Customers and businesses alike took to Twitter to say that the shopping centre had been shut and that those inside had been ordered to leave.

A Westfield spokeswoman said: "Westfield Stratford City had a partial evacuation today which was caused by contractors working in the centre accidentally setting off a fire alarm.

"The incident was fully investigated and was a false alarm.

"The centre was fully trading within 30 minutes."

The Met Police confirmed that the alarm had been reported at 10.40am, while a London Fire Brigade spokesman said that firefighters had not been sent to the scene.
