According to local reports, the man grabbed Bieber from behind. Security guards were right behind him and quickly grabbed the fan. Bieber freed himself and dashed to the side of the stage. The piano got turned over in the scuffle.
"A man ran on stage during Believe and tried to grab Justin and knocked the piano over. He was a fan," Bieber's rep tells E!. "Security detained the young man. All was fine and Justin continued the show."
According to local reports, the piano was unplayable for the rest of the show. After a three-minute break, Bieber returned to the stage for an encore and finished the concert with Boyfriend and Baby.
He tweeted later: "Dubai. Nothing stops the show."
