The sister-in-law of South Korean international Hwang Ui-jo was sentenced to three years in prison Thursday for posting private explicit videos of the footballer online and trying to blackmail him. The defendant, who has not been named, was accused of sharing the videos on social media while pretending to be an ex-girlfriend accusing him of infidelity. The release of the videos sparked a separate police investigation into the Nottingham Forest striker over whether the sexual encounters were filmed illegally without consent. Hwang has denied the allegations and prosecutors have yet to clear or formally charge him.
