DUBAI: The concert for massive international sensation Justin Bieber was moving along smoothly. Then all pandemonium was unleashed after a fan in Dubai rushed the stage, snuck through security and went after the teenage star. The fan attempted to tackle the 19-year-old singer during the middle of a song. He was unscathed by the incident and continued to sing throughout the incident, getting fans excited and impressed. "I think it is pretty amazing that he can continue to give us a concert even when a crazy guy is chasing him," Heba, a 20-year-old university student in Abu Dhabi told Bikyanews.com after the concert. UAE newspaper The National called the crazed fan "a male wearing a white shirt and jeans, who grabbed Bieber as he sang," but was quickly pinned down and dragged away by security. The singer came back on for an encore after a 3-minute break, finishing with his most popular song "Baby." BN
