Justin Bieber was attacked by a male fan during a piano performance on Dubai stage on Sunday.
Justin Bieber, 19, was performing one of his last songs, Believe, when a youth in a white shirt and jeans stormed onstage and grabbed singer from behind.
The blindsided Canadian star managed to free himself and dashed to the side of the stage.
Security guards rushed the stage and lunged at the attacker, according to a report in Dubai English language newspaper The National.
The attacker pushed the piano off its hinges and it fell damaged to the stage.
A video posted by a fan online showed security guards rushing around the stage as the piano lay upturned.
An accompanying tweet said: “Whoa. Crazy fan tackled @justinbieber and knocked the piano down the stage. Mayhem.”
According to reports, Justin Bieber was rattled, but he and his eight-piece band finished the song while the offender was taken off the stage.
After a three-minute break, Justin Bieber returned for an encore and finished the concert with Boyfriend and the finale Baby.
The singer also performed on Saturday in Dubai as part of his international Believe Tour and pulled a song out of respect for the country’s Muslim culture.
Justin Bieber skipped the song One Less Lonely Girl because the state religion of Islam frowns upon men touching women who are not their relatives.
The singer typically recruits a young female fan to join him during the song to flirt with onstage.
The respectful move followed another thoughtful incident on his international Believe Tour that occurred recently in Turkey.
Justin Bieber stopped his show multiple times on Thursday to allow fans to step away for the Muslim call to prayer.
