Our brief conversation was cut short when two girls rattled the lock on the fence surrounding the box hanging area.
Security went onto red alert as the two guards charged towards the fence, but they needn't have bothered since the girls just ran away giggling.
Movement spotted
There were about 400 people hanging around staring up at the wacky magician.

Then suddenly there was movement - Blaine stood up, and the crowd stirred.
He stretched, drank some water, put his jumper on, then knelt down under his blanket.
Toilet break?
