Those waiting in line to purchase the sequel to Apple's highly successful tablet had to follow new rules Apple had put in place for the launch, including issuing numbered wristbands that iPad 2 buyers had to wear. The store has been closed since the altercation while employees cleamed up the leftover mess. According to Chinese site MacX, the store looked like there had been a riot inside while several customers had blood on their faces. An unconfirmed report from Chinese blog Sinatech quoted a police source as saying that an Apple Store employee had beat up a jobless man who was acting as a scalper.
With a population of 1.2 billion, China is seen as a very important area by Apple. The country currently hosts 4 Apple stores and the company plans on building 25 more over the next few years.
