Biebers popularity has caused safety concerns. While promoting My World, Bieber was scheduled to appear at Long Island's Roosevelt Field Mall, but the performance had to be cancelled. The event got out of control, and over 35 units from the Nassau County and Garden City police departments had to be called in. Several fans received minor injuries. The police arrested Island Records senior vice-president, James A. Roppo, reportedly for hindering the police's crowd control efforts by not sending a timely message on Twitter as instructed by the police. James Roppo pleaded not guilty to all charges. On March 24 2010, Bieber's manager Scooter Braun, was arrested on one count of second-degree reckless endangerment and one count of second-degree criminal nuisance related to the incident. Braun pleaded not guilty to both charges and was later released.
On April 26, 2010, a scheduled promotional performance was cancelled by Australian police after several girls were injured in a crowd crush. Bieber was scheduled to sing three songs for the Channel Seven program, Sunrise. In a Twitter message after the incident, Bieber said: "I want to make this clear... I don't cancel.” Biebers tweet continued, stating: “I woke up this morning to the police canceling the show for safety reasons. I’m very happy about the welcome and the love from around the world, but I want everyone to still remember my fans safety comes first. At the end of the day I want you all to enjoy the music."
