Justin Bieber Arrest Warrant: Pop Star Detained In Rome For Alleged 2013 Paparazzi Attack

Canadian-born pop star Justin Bieber was hit with an international arrest warrant when he landed in Rome on Wednesday, local news outlet Roma reported. Local celebrity photographer Diego Pesoa is pressing charges against the “Beauty and a Beat” singer for an alleged attack in November 2013.

The photographer says he attempted to take a photo of the then 19-year-old Bieber outside a nightclub in Buenos Aires, Argentina. Pesoa claims Bieber, now 21, and one of his bodyguards lashed out at him outside the club in the city’s popular Palermo Hollywood neighborhood.

The court order came earlier this month from an Argentine judge after the singer failed to answer questions about the alleged assault. "I consider it pertinent to order the immediate detention of the accused," read Judge Alberto Julio Banos' order, issued April 8.

Bieber flew to Rome on Sunday from his home in Los Angeles to reportedly appear in the upcoming Ben Stiller film “Zoolander 2.” On Monday, Bieber created a post on his Facebook fan page, saying “working on something big right now in Europe. To learn more follow me on Fahlo. He is so hot right now.” (The last part refers to a catchphrase from the first “Zoolander” film.)

Italian police questioned the singer Wednesday, and a local news site reported that Bieber was not allowed to leave Italy. Investigators are deciding whether the Argentine judge's order is still applicable, questioning international agreements between the Argentina and Italy.

Bieber is known for confronting paparazzi in the past. In 2013, he was caught on video attempting to strike a photographer outside a hotel in London.

Various other incidents have also been captured on video.
