Police have questioned two senior officials of the General Association of Korean Residents in Japan (Chongryun) in connection with a suspected embezzlement case involving the failed Chogin Tokyo credit union, according to sources close to the case.

The former head of Chogin Tokyo, Chong Gyong Saeing, 64, and several others are suspected of embezzling about 1 billion yen from the credit union by fabricating loans.

Investigators suspect that more than 20 percent of funds thought to have been embezzled by Chong and the others went to Chongryun, the pro-Pyongyang group of Korean residents here.
