Tech issues behind Bieber delay

Justin Bieber has blamed "technical issues" for making him late to the stage in London on Monday night.

The 'Boyfriend' singer caused uproar as fans waited nearly two hours for him to begin his 'Believe' concert at The O2 arena, but the pop star has claimed the delay was out of his control due to unidentified problems and insisted he was only 40 minutes late for his performance.
