Prosecutors on Wednesday afternoon served a fresh arrest warrant on a former chief of KSD, a government-linked group that provides industrial accident insurance to small businesses, on suspicion of breach of trust, investigative sources said.

The Tokyo District Public Prosecutor's Office suspects that Tadao Koseki, former KSD president and founder, caused KSD Homeikai, a voluntary association, to suffer 100 million yen in losses by forcing the organization to purchase around 150,000 CDs of a female Japanese singer who appears in a KSD advertisement, the sources said.

According to the sources, Koseki, 79, as president of KSD Homeikai, ordered the association to purchase the singer's CDs on three occasions coinciding with her latest releases between 1998 and this year and to give them away to members as part of a welfare program.
