Justin Bieber's airport clash after fleeing mob

Justin Bieber clashed with an onlooker as he fled a mob of screaming girls in the U.K. on Monday (23Apr12).

The Baby hitmaker jetted into Britain overnight on Sunday (22Apr12) but after touching down at London's Heathrow Airport, he was met with dozens of hysterical teenage girls.

As he tried calmly to pose for pictures with his fans, a lone security guard struggled to control the crowd, and Bieber was eventually forced to break into a run in a bid to flee to safety.

As he did so, a passer-by who was taking pictures of the mayhem inadvertently got in the young singer's way, and Bieber careered into him, sending the man's camera smashing to the ground.

But the teen idol clearly saw the funny side of the whole incident, as he later took to his Twitter.com blog to write, "Wow. Airport was crazy getting to London! All worth it for my beliebers. Some people always tryna (trying to) ruin it for the fans. Not today Swaggy."
