Justin Bieber is being summoned for questioning by an investigative judge in Argentina.
Bieber has been accused of sending bodyguards to attack a photographer outside a Buenos Aires nightclub during a South American tour last year.
Judge Facundo Cubas asked Interpol today to use all "necessary means" to notify the singer that he has 60 days to appear before the court in Argentina. The judge says that if Bieber fails to comply, an international arrest order will be issued.
Argentinian photographer Diego Pesoa alleges he was chased and beaten on November 9 last year by Bieber's bodyguards outside the INK nightclub, where the singer and his entourage were partying.
Bieber would face up to one year in prison if he was convicted on a charge of causing minor injuries.
