Justin Bieber Arrested in Miami Beach, Charged With DUI and Resisting Arrest

Bieber was arrested Jan. 23 in Miami Beach after what police described as an illegal street race between Bieber and a friend.

Alcohol breath tests found Bieber's level below the 0.02 limit for underage drivers, but urine tests showed the presence of marijuana and an anti-anxiety drug. Bieber also was charged with driving on an expired license.

It's unknown whether Bieber will attend next week's hearing.
