The Aichi Prefectural Police on Thursday arrested seven key figures of an organization that allegedly took over bank accounts to sell them to criminal groups.

The organization, led by Yusuke Nishikawa, 32, who is among the seven individuals, is believed to be one of the biggest of its kind in Japan, handling over 1,000 accounts annually for the purpose of money laundering.

The seven are accused of fraud and violation of the law for the prevention of transfer of criminal proceeds. They allegedly sold stolen accounts not only in Japan but also to a Chinese fraud group based overseas.
