Bieber fever descends on Chile

Justin Bieber fever has descended on Chile with hundreds of excited, screaming fans mobbing his hotel.

The singer is in the city of Santiago, for the latest leg of his My World Tour.

According to TMZ's sources the mob scene prompted local authorities to contact Bieber's camp and order him to come to the hotel by helicopter, because they feared they couldn't control the crowd.

The visit has not been without its controversy with Bieber forced to call for calm after frustrated paparazzi kicked and punched the car he was travelling in.
