A South Korean court has sentenced a woman who blackmailed football star Son Heung-min to four years in prison. The woman in her 20s and her accomplice, a man in his 40s, were found guilty of blackmailing the former Tottenham captain by saying she was pregnant with his child. The woman had approached Son sometime last year claiming she was carrying his child, when in fact she did not know whether that was the case, a Seoul district court heard, according to local media. She extorted $300 million won ($200,000; £153,000) from him and threatened to go public with the allegation if he did not comply. The woman spent the money on luxury and designer goods, AFP news agency reported. Prosecutors argued that she portrayed herself as a victim but thoroughly planned the crime. Her accomplice, who had threatened Son 15 times to get the money, received a two-year sentence for attempted blackmail. When they demanded additional money this year, Son reported them to the police. The judge noted that the woman and her accomplice had exploited Son's celebrity and remarked on the intense mental anguish he endured following the incident. Recently, Son was named the second-highest paid footballer in Major League Soccer (MLS), North America's top-tier league, after leaving Tottenham for Los Angeles Football Club for a record transfer. Widely regarded as one of Asia's best football stars, Son is extremely popular in his home country.
