Known Canadian, convicted criminal and pop "singer" Justin Bieber is in bother with the law again.

The 20-year old musician - no, can't do it, sorry - celebrity is at the centre of an investigation by Argentine authorities, relating to an alleged assault in Buenos Aires in 2013.

According to local magistrate's report, photographer Diego Pesoa was chased and beaten by Bieber and his entourage following an attempt by Pesoa to take pictures at a nightclub.

Pesoa's lawyer claims that Bieber ordered his heavies to attack and beat the photographer.

Local magistrates have ordered Interpol to use "all necessary means" to bring Bieber to Argentina to face questioning on the alleged incident.

Bieber has yet to respond to the allegations.
