The article specifically says that 6 people are alleged to have shown up with badges, claiming to be with the police. So it can't be explained away as one old nutjob reliving the glory days of busting down doors and roughing up perps.
That said, we do need more information. The entire basis for this story is one person's account and the actual police saying they had nothing to do with it. The only corroborating evidence is a phone number that the "police" left that belongs to an Apple employee. The again, who knows how he actually got the number.
It's too early to jump all over Apple based on so little evidence, but the whole thing sounds pretty shady. If it does turn out they did this they need to suffer.
