Justin Bieber has become a wanted man in Argentina after failing to return to Buenos Aires for police questioning in relation to an alleged attack on a local paparazzo in 2013.

Back in November (14), a judge set a 60-day deadline for the pop superstar to appear before a court in the country, or face having an international warrant issued for his arrest over the alleged assault of photographer Diego Pesoa a year before (Nov13).

Pesoa claims the singer's bodyguards attacked him on Bieber's orders as he attempted to snap pictures of the Baby hitmaker leaving a nightclub while on tour in Argentina, and had to seek hospital treatment for his injuries.

Buenos Aires investigators have been wanting to speak to Bieber ever since Pesoa filed a police report, but the 21 year old appears to have ignored the requests and now Judge Alberto Julio Banos is demanding he be taken into custody if he steps foot in Argentina again.

Issuing the warrant for the singer and one of his bodyguards on Wednesday (08Apr15), the judge stated, "I consider it pertinent to order the immediate detention of the accused."

Bieber could face up to a year behind bars if he is charged with causing minor injuries.
