A local photographer, Diego Pesoa, accused Bieber and one of his bodyguards of lashing out at him when he tried to take a picture of the star as he left the club in the capital’s trendy Palermo Hollywood neighborhood.
Entertainment website FarandulaShow (www.farandulaShow.com) posted a copy of the court ruling ordering Bieber be detained on its web page. Court secretary Soledad Nieto, a co-signatory of the order paper, confirmed the document was authentic.
“I consider it pertinent to order the immediate detention of the accused,” read Judge Alberto Julio Banos’ order, which is dated April 8.
The court also ordered the detention of one of Bieber’s bodyguards.
In November, another local judge magistrate had ordered Bieber to appear for questioning within two months over the same alleged incident and requested the assistance of Argentina’s Interpol branch to help locate the 21-year-old.
Bieber has had a string of run-ins with the law in several countries.
Bieber’s representatives did not immediately reply to a request for comment.
