The two were charged with misdemeanors after police said they refused to help disperse a rowdy crowd at a New York mall in 2009. Thousands of unruly girls turned up at a Long Island clothing store to see the teen pop star sign autographs. Police hadn't been expecting the crowd, and ordered the event cancelled.
Def Jam Records executive James Roppo was arrested after police said he refused to help disperse the crowd. Months later, police also pressed child endangerment charges against Bieber's manager, Scott Braun.
Prosecutors announced Friday they were dropping the charges. They say having Bieber educate kids about bullying is invaluable.
