YouTuber arrested for allegedly using AI to defame Korean actor

South Korean authorities have arrested a YouTuber who allegedly made defamatory claims about actor Kim Soo-hyun, fuelling a scandal that halted the A-lister's career.Police and prosecutors allege that Kim Se-ui, who runs the popular YouTube channel Hover Lab, had manipulated evidence to falsely claim that Kim Soo-hyun had dated an actress while she was a minor - allegations that the actor has always denied.The Seoul Central District Court granted an arrest warrant for the YouTuber on Tuesday, citing concerns that he might destroy evidence or flee.In a statement on Wednesday, Kim Soo-hyun's agency said that the "truth has been proven"."The investigation confirmed that all suspicions and evidence raised by Hover Lab against Kim Soo-hyun were unfounded," said the statement, which also thanked the supporters who had stood by the actor.Speaking to reporters outside the court on Tuesday, ahead of the court's decision, YouTuber Kim Se-ui denied the charges and said the warrant "did not even properly organise the basic facts".He said he would lodge complaints against the police and prosecutors who requested his arrest.The allegations against Kim Soo-hyun surfaced last year, shortly after actress Kim Sae-ron killed herself at the age of 24.
