Justin Bieber performed a free six-song concert yesterday in Oslo, Norway that nearly caused a state of emergency. Swarms of people rushed the venue, a dozen fans passed out, and there were 88 reported hospital visits. The concert slowed mobile service in the area, but Instagrammers were still able to capture some pictures of the chaotic event.
