Justin Bieber trapped in UK hotel?

Police have been sent to calm down fans outside of Justin Bieber's hotel in Liverpool, England.

Bieber is currently trapped inside of his hotel room as numerous fans outside the building are causing a possible riot situation, according to Gossip Cop.

Authorities have reportedly warned that they could arrest the popstar if he or his entourage goes up to the balcony where fans could get a view of them.

Bieber's manager Scooter Braun has said that his team is "complying with all law enforcement demands" as officials try to get the situation under control.

The singer posted a picture on Twitter of fans raging outside of the hotel's front doors.

"This is crazy. There are like thousands of people out there. love everybody but gonna try and get some sleep. please dont scream. Lol (sic)," Bieber tweeted earlier today, apparently in reference to the mob outside of his hotel.
