South Korea extends jail term for former Olympic coach

The former coach convicted of physically abusing South Korean double Olympic short-track gold medallist Shim Suk-hee had his prison sentence increased to 18 months today.

Cho Jae-beom was initially sentenced to 10 months last year, but the Suwon District Court extended his term after Shim testified at an appeal hearing.

The 22-year-old elite athlete has four Olympic medals to her name, including relay golds at both Sochi 2014 and on home ice last year

The case, and an accusation that he had also sexually abused the athlete has triggered South Korea's largest investigation into the assault and sexual assault in sports after the events unleashed a wave of similar accusations.

The case made headlines because speed skating has a huge and devoted following in South Korea, which has won 24 gold medals since speed skating became an Olympic sport in 1992, more than any other country.

In September, a lower court had jailed the former national coach, Cho Jae-Beom, for 10 months on a conviction of assaulting Olympic champion Shim Suk-hee, 21.

"The defendant ... has shown regret but has severely hit the victim with his fists and feet ever since the victim was young, taking as the reason a slack attitude during training," the Suwon District Court said in its ruling.

The prosecution had sought a two-year sentence on the charges, which Cho had admitted.

Besides the assault charges, police are investigating accusations Shim made in December, saying Cho had sexually assaulted her from the time she was 17.

Cho has been questioned twice in January on the sex abuse accusation at a detention center where he is being held, a police official said.

He has not been charged on the sex abuse allegations.

Cho denies the accusation of sexual abuse, his lawyer Oh Dong-Hyun has said.

Since the case provoked national outrage, more athletes in other sports, such as judo and archery, have come forward with accounts of assault and sexual abuse, media have said.

On Friday, South Korea announced steps such as a government inquiry with the National Human Rights Commission to investigate conditions for about 63,000 student-athletes, as well as possible public funding cuts for any sport facing public outcry.
