‘Memba back in November of 2009, when a crowd of teenagers got out of control before Justin Bieber was supposed to meet and greet a few fans at the Roosevelt Field Mall? Well, it happened again, this time in Sydney, Australia.

As we’ve all come to expect by now, thousands of frenzied teens who spent the night camped out by Sydney Harbor waiting for a glimpse of [lastfm]Justin Bieber[/lastfm], surged toward the venue on Monday morning, sending at least eight already crying girls to the hospital and injuring several more.

Police canceled the performance after the swarm, which may have begun when rumors spread that the singer had arrived early. “They wouldn’t listen to our directions, so hence they left us with no option,” Deputy Commissioner Dave Owens told reporters, adding it was a concern that so many youngsters were out at night without their parents.

In the crush, at least ten girls fainted and paramedics had to pull them out of the crowd, presumably using boomerangs tied to rope. Bieber took to his Twitter page to apologize for the cancelation and to thank his fans for being so understanding:

“I love my fans….and I am just as disappointed as everyone else with the news from this morning. I want to sing for my fans.”

“I WANT TO MAKE THIS CLEAR…I DONT CANCEL…I WOKE UP THIS MORNING TO THE POLICE CANCELING THE SHOW FOR SAFETY REASONS.”

“I’m beyond grateful…that was incredible. Thank u for such an amazing warm welcome Australia…I told you I wouldnt let you down. Thank U!”

“…at the end of the day I want you all to enjoy the music…Im very proud of this album and I want you all to enjoy it….”

“with everything that happened 2day i want u all 2 know i care and U all rule and if i could thank every 1 of u individually i would.”

After all of the insanity, Justin performed behind some safety glass on the “Sunshine” program. Check out video and photos from the show below.
