Coldplay's road crew caused a double evacuation of BBC Broadcasting House in London last week, it's emerged.

Lighting technicians are understood to have caused fire alarms to go off as they prepared the bands equipment.

Two of the BBC's radio stations – Radio 4 and Radio 4 – were taken off air momentarily during the incidents.

But Coldplay were finally able to record their set, which aired on Saturday.

The band return to the UK in December for a full UK tour in support of their latest album 'Viva La Vida or Death and All His Friends'.
