In the video shown below, you can hear the Apple store employee saying that these guys might steel something. After that, the black school boys were told that it was end of discussion and can leave.
Funny thing is that they were not even inside the store. The black boys were not very happy with Apple store employee’s treatment but Apple has issued an apology to take care of the situation.
The black boys are chilled too with one of them saying on Facebook that since Apple has apologized, they are chilled about it and there is no end to elongate this. Via bbc.
Racism is bad and whosoever did this should feel bad about it. In my experience, white people, or "people" in general aren’t treated much better in an Apple Store.
