MIAMI (AP) - A South Florida judge has delayed the trial of pop star Justin Bieber on charges of driving under the influence, resisting arrest and driving with an expired license until July. Miami-Dade County Judge William Altfield on Wednesday granted a motion for a postponement sought by Bieber's lawyers. His attorney Roy Black said more time was needed to examine evidence and make decisions about how to proceed. The trial was delayed from May 5 to July 7. The 20-year-old singer was arrested Jan. 23 in Miami Beach after what police described as an illegal street drag race. He wasn't charged with drag racing. Alcohol breath tests found Bieber's level below the 0.02 limit for underage drivers. Urine tests showed the presence of marijuana and an anti-anxiety drug in his system.
