CHARLOTTE, N.C./WASHINGTON, D.C. (Reuters) - Anonymous, a hacker group sympathetic to WikiLeaks, plans to release e-mails obtained from Bank of America Corp early Monday morning, according to posts on the group's Twitter feed.

The group, unrelated to the document leak website founded by Julian Assange, said it plans to release documents exposing "corruption and fraud" at the largest U.S. bank by assets.

A representative of Anonymous said the documents relate to the issue of whether Bank of America has improperly foreclosed on homes. The representative added that he had not seen the documents, but he has been briefed on their contents.

A Bank of America Corp spokesman said the documents were non-foreclosure related clerical and administrative documents stolen by a former Balboa Insurance employee.

The division -- which BofA has since agreed to sell to Australian insurer QBE Insurance Group -- provides mortgage and auto insurance for banks, and provides home insurance for consumers.

"We are confident that his extravagant assertions are untrue," the spokesman said.
