A woman who blackmailed South Korean football superstar Son Heung-min by claiming she was the mother of his child was jailed for four years on Monday.

The woman, surnamed Yang, extorted 300 million won ($200,000) from Son last year by threatening to go public. She splurged the cash on luxury goods, before she and an accomplice surnamed Yong tried to extort a further 70 million from the Los Angeles FC star. Son contacted the police, leading to their arrest.
