NEW YORK (AP) -- The Justice Department says it has closed its investigation into the collapse of Washington Mutual without any criminal charges filed.
In September 2008, the federal government seized Washington Mutual's flagship bank, based in Seattle, and sold its assets to JPMorgan Chase & Co. for $1.9 billion. It was the biggest bank failure in U.S. history.
Justice, the FBI and the Securities and Exchange Commission opened investigations into Washington Mutual's collapse in October.
Justice says that after an "extensive investigation that included hundreds of interviews and the review of millions of documents," there are not grounds for criminal charges.
In July, WaMu and other defendants agreed to pay $208.5 million to investors to settle a class-action lawsuit stemming from the lender's collapse.
