The current and former chairmen of a pro-Pyongyang credit union association in Japan were arrested Wednesday on suspicion of causing financial damage to a credit union serving Korean residents.

Li Jong Ho, 60, chairman of the Korean Credit Unions' Association in Japan, and his predecessor, Li Bom Rak, 67, are suspected of a breach of trust over damages inflicted on Chogin Kinki Credit Cooperative, which collapsed in December 2000.

An Jong Ji, 55, and Song Han Gyong, 61, former Chogin Kinki presidents, were arrested in November on suspicion of withholding data in a 2000 government probe as well as committing another breach of trust. They are also suspected of conspiring with the chairman and former chairman of the association, investigators said.

The two presidents , whose detention periods expired Wednesday, will be served new arrest warrants once they are indicted, they said.
