The Yonhap news agency reported Thursday that the K-League club terminated Kim's contract because he allegedly bet on the outcome of one of the Steeler's matches two months ago.

Five players from different clubs have been arrested and charged with taking money from gambling brokers and allegedly making deliberate mistakes that led to their teams losing, according to domestic media.

Jeong Jong-kwan, a former K-League player, was found dead this week in an apparent suicide. He left a note claiming his involvement in match-fixing schemes, Yonhap reported.

The latest allegations have unfolded this week as football's international governing body has been mired in its worst corruption scandal, with two senior executive members suspended amid bribery allegations relating to the vote for the FIFA presidency.

Asian Football Confederation chief Mohamed bin Hammam withdrew as a candidate for the FIFA presidency on the weekend and was later provisionally suspended by an ethics committee pending an investigation into allegations of bribery.

But South Korean football has been absorbed in its own trouble, far from the troubled FIFA congress in Zurich.

Kim Jung-kyum, whose contract with one of the league's biggest clubs was set to expire this year, joined the K-League in 1999 with the Chunnam Dragons; he played 226 career games with three different clubs, Yonhap said.

South Korea's top football league has promised to crack down on players suspected of match fixing. About 1,000 officials gathered at an emergency workshop this week to consider ways to stop match fixing and illegal betting.

Military prosecutors, meanwhile, have sought an arrest warrant for former national player Kim Dong-hyun.

Kim Dong-hyun is suspected of receiving tens of millions of won for participating in match-fixing during his service, Yonhap reported. He enlisted for compulsory military service in 2009.

Defense Ministry spokesman Kim Min-seok told reporters that a military court will review the warrant request, according to Yonhap. "If the warrant is issued, Sgt. Kim will be immediately arrested," he said.
