What I read and heard from the news reports were that the police were called to a club for a disturbance. While they were arresting the people involved in the disturbance Nick Carter started arguing, not fighting, with a women. He was asked to leave but didn't and was placed under arrest.
I just gave my daughter for one of her Christmas presents the April 28, 2002 cruise. We gave it to her because Nick and Arron Carter were going to be sailing on that date and she listens to both of their music.
I am hoping that Nick is not the next BSB to "go into rehab."
