According to a report from the Austrian Times, Bieber's crew rolled into the popular Passage club where the entourage began to cause a disturbance.
According to management, Bieber's bodyguards reportedly smashed fans' cameras and broke mobile phones for taking photos of the star. One reportedly even groped a young female fan, who left the venue in tears.
In response, club manager Joachim Bankel responded, "Justin Bieber is no longer welcome here".
Sounds fair. It's been a lousy run for 19-year-old Justin, with media tensions, his Paris eviction, his London pap attack, and this past weekend, his pet monkey being seized by German officials and more.
Most seriously, Justin is currently facing battery charges after it was alleged that he spat in his neighbour's face and threatened him.
Is Bieber cracking up? Are we looking at another Lindsay Lohan-like meltdown in progress?
