A hard-line group called the Islamic Defenders Front has purchased 150 tickets to upcoming Lady Gaga concert, and they promoise/threaten to stop the show.

A spokesman for the group posted on his Facebook account a picture of a member, wearing a turban and sunglasses to conceal his face, holding a ticket.
The photo's caption said, "We have gotten Lady Gaga tickets, not to watch [the concert] but for us to enter. Whatever will be will be, we're ready for the risk."
He claims the group was ready to stop the concert, but he stressed that they would not attack the audience. The only target was Lady Gaga and her crew.
