According to a statement given to The Hollywood Reporter from Bieber's reps, the pop star he was held three to four hours before being let go. No word on why he was originally detained though as THS points out, it is standard procedure for non-citizens to be detained by Immigration and Customs Enforcement (ICE) upon entering the U.S. if they have committed a prior crime.

Earlier that same day, Bieber's trial for driving under the influence in Miami was delayed until July after his lawyers reportedly asked for more time to examine evidence and discuss whether to accept a possible plea deal.
