Ottawa (BFT): An Argentinian investigative judge has said there is enough evidence against pop star Justin Bieber to question him in a criminal case. Bieber is accused of sending bodyguards to attack a photographer outside a Buenos Aires nightclub during a 2013 tour. Judge Facundo Cubas said that footage and photos show that Bieber ordered bodyguards to chase down the photographer to take away his camera. Judge Cubas has summoned Bieber for questioning and asked Interpol to notify the singer.
