Justin Bieber kicked up a storm today as thousands of young, screaming fans overwhelmed and overpowered the police in Oslo, Norway.
The Canadian singer is in the country to perform what was supposed to be a secret and free concert in the Norwegian capital, however, local police are threatening to issue a state of emergency and cancel the event due to the fans.
Beliebers from across Europe had moved in swarms to Oslo Airport on Tuesday, then headed over to the star's rumoured hotel and set up camp.
The large number of fans took police by surprise and as more and more girls turned up, the boys in blue were forced to call in reinforcements.
