Justin Bieber arrested? Well… no. Someone at a Justin Bieber event this afternoon, did, however, get arrested following an all-out mob scene that resulted in the cancellation of his appearance.

Justin Bieber fans appeared in droves – and the crowd got crazy it seems – at an appearance by the 15-year-old singer at the Roosevelt Field Mall on Long Island.

Justin Bieber took to Twitter to relay the events, which included this tweet at 4:30 p.m. ET: “they are not allowing me to come into the mall. if you dont leave I and my fans will be arrested as the police just told us.”

At about 4:32 p.m., Justin’s tweet read: “the event at roosevelt mall is cancelled. please go home. the police have already arrested one person from my camp. I dont want anyone hurt.”

10,000 fans reportedly showed up to see Justin Bieber.
