(Jan. 24) The Securities and Exchange Commission has charged 13 more people with aiding the earlier financial fraud at Columbia, Md.-based U.S. Foodservice, a subsidiary of Dutch grocery retailer Royal Ahold NV, Reuters reported.

Reportedly, the 13 accused vendor employees and agents signed and returned false audit confirmations at the request of U.S. Foodservice auditors.

That may have enabled the firm to inflate its income by at least $700 million during fiscal 2001 and 2002, resulting in Ahold misrepresenting its earnings.

The Roanoke (Va.) Times reported that, in all, 30 people have been accused in connection with the scandal, which led to the resignation of top executives, and criminal investigations in the U.S. and the Netherlands.
